DETAILED DESCRIPTION

FIGS. 1A and 1B depict an example motorized window treatment 100 (e.g.,a battery-powered motorized window treatment system) that includes aroller tube 110 and a flexible material 120 (e.g., a covering material)windingly attached to the roller tube 110. The motorized windowtreatment 100 may be a window treatment assembly that includes a rollertube assembly 111 and one or more mounting brackets 130A, 130B. Theroller tube assembly 111 may include a roller tube 110, a flexiblematerial 120, a motor drive unit 151 at a first end 112 of the rollertube assembly 111, and an idler end (not shown) at a second end 114 ofthe roller tube assembly 111. The mounting brackets 130A, 130B may beconfigured to be coupled to or otherwise mounted to a structure. Forexample, each of the mounting brackets 130A, 130B may be configured tobe mounted to (e.g., attached to) a window frame (e.g., to a head jambor side jambs of the window frame), a wall, a ceiling, or otherstructure, such that the motorized window treatment 100 is mountedproximate to an opening (e.g., over the opening or in the opening), suchas a window for example. The mounting brackets 130A, 130B may beconfigured to be mounted to a vertical structure (e.g., wall-mounted toa wall as shown in FIG. 1A) and/or mounted to a horizontal structure(e.g., ceiling-mounted to a ceiling). For example, the mounting brackets130A, 130B may be rotated 90 degrees from what is shown in FIG. 1A.

The roller tube 110 may operate as a rotational element of the motorizedwindow treatment 100. The roller tube 110 may be elongate along alongitudinal direction L and rotatably mounted (e.g., rotatablysupported) by the mounting brackets 130. The roller tube 110 may definea longitudinal axis 116. The longitudinal axis 116 may extend along thelongitudinal direction L. The mounting bracket 130A may extend from thestructure in a radial direction R, as shown in FIG. 1B. It should beappreciated that when the mounting brackets 130 are ceiling-mounted, themounting bracket 130A may extend from the structure in a transversedirection T. The radial direction R may be defined as a directionperpendicular to the structure and the longitudinal axis 116. Theflexible material 120 may be windingly attached to the roller tube 110,such that rotation of the roller tube 110 causes the flexible material120 to wind around or unwind from the roller tube 110 along a transversedirection T that extends perpendicular to the longitudinal direction L.For example, rotation of the roller tube 110 may cause the flexiblematerial 120 to move between a raised (e.g., open) position (e.g., asshown in FIG. 1A) and a lowered (e.g., closed) position along thetransverse direction T.

The roller tube 110 may be made of aluminum. The roller tube 110 may bea low-deflection roller tube and may be made of a material that has highstrength and low density, such as carbon fiber. The roller tube 110 mayhave, for example, a diameter of approximately two inches. For example,the roller tube 110 may exhibit a deflection of less than ¼ of an inchwhen the flexible material 120 has a length of 12 feet and a width of 12feet (e.g., and the roller tube 110 has a corresponding width of 12 feetand the diameter is two inches). Examples of low-deflection roller tubesare described in greater detail in U.S. Patent Application PublicationNo. 2016/0326801, published Nov. 10, 2016, entitled LOW-DEFLECTIONROLLER SHADE TUBE FOR LARGE OPENINGS, the entire disclosure of which ishereby incorporated by reference.

The flexible material 120 may include a first end (e.g., a top or upperend) that is coupled to the roller tube 110 and a second end (e.g., abottom or lower end) that is coupled to a hembar 140. The hembar 140 maybe configured, for example weighted, to cause the flexible material 120to hang vertically. Rotation of the roller tube 110 may cause the hembar140 to move toward or away from the roller tube 110 between the raisedand lowered positions.

The flexible material 120 may be any suitable material, or form anycombination of materials. For example, the flexible material 120 may be“scrim,” woven cloth, non-woven material, light-control film, screen,and/or mesh. The motorized window treatment 100 may be any type ofwindow treatment. For example, the motorized window treatment 100 may bea roller shade as illustrated, a soft sheer shade, a drapery, a cellularshade, a Roman shade, or a Venetian blind. As shown, the flexiblematerial 120 may be a material suitable for use as a shade fabric, andmay be alternatively referred to as a flexible material. The flexiblematerial 120 is not limited to shade fabric. For example, in accordancewith an alternative implementation of the motorized window treatment 100as a retractable projection screen, the flexible material 120 may be amaterial suitable for displaying images projected onto the flexiblematerial 120.

The motorized window treatment 100 may include a drive assembly (e.g.,such as the motor drive unit 690 shown in FIG. 8A). The drive assemblymay at least partially be disposed within the roller tube 110. Forexample, the drive assembly may be retained within a motor drive unithousing (e.g., such as the motor drive unit housing 680 shown in FIG.8A) that is received within the roller tube 110. The drive assembly mayinclude a control circuit that may include a microprocessor and may bemounted to a printed circuit board. The drive assembly may be powered bya power source (e.g., an alternating-current or direct-current powersource) provided by electrical wiring and/or batteries (e.g., as shownin FIGS. 2A-6). The drive assembly may be operably coupled to the rollertube 110 such that when the drive assembly is actuated, the roller tube110 rotates. The drive assembly may be configured to rotate the rollertube 110 of the example motorized window treatment 100 such that theflexible material 120 is operable between the raised position and thelowered position. The drive assembly may be configured to rotate theroller tube 110 while reducing noise generated by the drive assembly(e.g., noise generated by one or more gear stages of the driveassembly). Examples of drive assemblies for motorized window treatmentsare described in greater detail in commonly-assigned U.S. Pat. No.6,497,267, issued Dec. 24, 2002, entitled MOTORIZED WINDOW SHADE WITHULTRAQUIET MOTOR DRIVE AND ESD PROTECTION, and U.S. Pat. No. 9,598,901,issued Mar. 21, 2017, entitled QUIET MOTORIZED WINDOW TREATMENT SYSTEM,the entire disclosures of which are hereby incorporated by reference.

The motorized window treatment 100 may be configured to enable access toone or more ends of the roller tube 110 while remaining secured to themounting brackets 130A, 130B. For example, the motorized windowtreatment 100 may be adjusted (e.g., pivoted or slid) between anoperating position (e.g., as shown in FIG. 1A) to an extended position(e.g., as shown in FIG. 1B) while secured to the mounting brackets 130A,130B. The operating position may be defined as a position in which theroller tube 110 is supported by and aligned with both mounting brackets130A, 130B. The extended position may be defined as a position in whichone or more ends of the roller tube 110 are accessible while stillattached to the brackets 130A, 130B. Operation of the motorized windowtreatment 100 may be disabled when it is adjusted between the operatingposition and the extended position. For example, operation of themotorized window treatment 100 may disabled when the extended positionis reached. Alternatively, operation of the motorized window treatment100 may be disabled at some point between the operating position and theextended position, for example, when the motorized window treatment 100exits the operating position. Operation of the motorized windowtreatment 100 may be enabled when it enters the operating position.

When in the extended position, the one or more ends of the roller tube110 may be accessed, for example, to replace batteries, adjust one ormore settings, make an electrical connection, repair one or morecomponents, and/or the like. One or more of the mounting brackets 130A,130B may enable an end of the roller tube 110 to be accessed when themotorized window treatment is in the extended position. One or more ofthe mounting brackets 130A, 130B may include a sliding portion to enablethe end of the roller tube 110 to be accessible. For example, a firstportion (e.g., sliding portion) of one or more of the mounting brackets130A, 130B may extend from a second portion (e.g., fixed portion). Forexample, a sliding portion of one or more of the mounting brackets 130A,130B may be adjusted with respect to a fixed portion, for example, toexpose a respective end of the roller tube 110.

One end of the roller tube may slide out when the motorized windowtreatment is in the extended position. For example, one of the mountingbrackets (e.g., mounting bracket 130A) may be configured to slide outand the other one of the mounting brackets (e.g., mounting bracket 130B)may remain stationary when the motorized window treatment 100 (e.g., theroller tube 110) is in the extended position, for example, as shown inFIG. 1B. The extended position of the motorized window treatment 100 mayinclude a first end 112 of the roller tube assembly 111 proximate to afirst mounting bracket (e.g., mounting bracket 130A) being further froma window and/or the structure to which the first mounting bracket isanchored than when the motorized window treatment 100 is in theoperating position. A second end 114 (e.g., opposite the first end 112)of the roller tube assembly 111 proximate to the second mounting bracket(e.g., mounting bracket 130B) may remain substantially fixed when themotorized window treatment 100 is in the extended position, for example,as shown in FIG. 1B. Stated differently, the roller tube 110 may pivotbetween the operating position and the extended position. The second end114 of the roller tube 110 and the mounting bracket 130B may define afulcrum about which the motorized window treatment 100 (e.g., the rollertube 110) pivots.

Alternatively, both ends of the roller tube may slide out when themotorized window treatment is in the extended position. For example,both of the mounting brackets 130A, 130B may be configured to slide out.That is, both of the mounting brackets 130A, 130B may include slidingportions. In this configuration, both the first end 112 and the secondend 114 may be further from the window and/or the structure when themotorized window treatment 100 is in the extended position. Stateddifferently, the motorized window treatment 100 may slide between theoperating position and the extended position. When both ends of theroller tube are configured to slide out, two people may be required tooperate the motorized window treatment 100 between the operatingposition and the extended position.

When the motorized window treatment 100 is in the extended position, amotor drive unit housing end 150 of the motor drive unit 151 (e.g., thecap 250 shown in FIGS. 2A and 2B) may be exposed (e.g., accessible). Themotor drive unit housing end 150 may be located proximate to the firstend 112 of the roller tube assembly 111. The motor drive unit housingend 150 may cover a cavity of the roller tube 110. The motor drive unithousing end 150 may be configured to be removably secured to the rollertube 110 (e.g., the first end 112 of the roller tube assembly 111). Forexample, the motor drive unit housing end 150 may be configured to besecured within the cavity. The motor drive unit housing end 150 may beconfigured to retain one or more components (e.g., such as the batteries260 shown in FIGS. 2A and 2B).

The motor drive unit housing end 150 may include a control button 152.The control button 152 may be backlit. For example, the control button152 may include a light pipe (e.g., may be translucent or transparent)that is illuminated by a light emitting diode (LED) within the motordrive unit housing. The control button 152 may be configured to enable auser to configure (e.g., change one or more settings, associate, etc.)the drive assembly of the motorized window treatment 100. For example,the control button 152 may be configured to change one or more wirelesscommunication settings and/or one or more drive settings. The controlbutton 152 may be configured to enable a user to pair the motorizedwindow treatment 100 with a remote control device to allow for wirelesscommunication between the remote control device and a wirelesscommunication circuit (e.g., an RF transceiver) in the motor drive unithousing end 150. The control button 152 may be configured to providefeedback (e.g., a status indication) to a user. For example, the controlbutton 152 may be configured to flash and/or change colors to providethe status indication to the user. The status indication may indicatewhen the motorized window treatment 100 is in a programming mode.

The motor drive unit housing end 150 may include a disable actuator 154for detecting when the roller tube 110 is not in the operating position.The drive assembly may be deactivated (e.g., automatically deactivated)when the roller tube 110 is not in the operating position. For example,the disable actuator 154 may be configured to deactivate the driveassembly such that the covering material cannot be raised or loweredwhen the roller tube 110 is not in the operating position. The disableactuator 154 may disable the operation of a motor of the drive assembly,for example, when the roller tube 110 is pivoted (e.g., or slid) fromthe operating position to the extended position. The disable actuator154 may enable the operation of the motor when the roller tube 110reaches the operating position. For example, the disable actuator 154may be a button, a switch, and/or the like.

In addition, the motor drive unit housing end 150 may also comprise aposition detect circuit (not shown) for detecting when the roller tube110 is not in the operating position and deactivating (e.g.,automatically deactivating) the drive assembly (e.g., rather thanincluding the disable actuator 154). For example, the position detectcircuit may comprise a magnetic sensing circuit (e.g., a Hall-effectsensor circuit) configured to detect when the motor drive unit housingend 150 is in the extended position and not in close proximity to amagnet (e.g., such as magnet 675 shown in FIG. 8B) located inside of themounting bracket 130A. For example, the position detect circuit maydetect proximity of the magnet to the motor drive unit housing end 150.The position detect circuit may be configured to disable the driveassembly such that the covering material cannot be raised or loweredwhen the roller tube 110 is not in the operating position. The positiondetect circuit may disable a motor of the drive assembly, for example,when the roller tube 110 is pivoted (e.g., or slid) from the operatingposition to the extended position. The position detect circuit mayenable the motor when the roller tube 110 reaches the operatingposition. For example, the position detect circuit may also comprise anIR sensor, a switch, and/or the like.

Thecap 350 may be removably secured to the end 312 of the roller tube 310.Alternatively, the cap 350 may be removably secured to the motor driveunit housing (e.g., such as the motor drive unit housing 680 shown inFIG. 8A).

The batteries 360 may be configured to be removed from the cavity 311along the longitudinal axis 316 of the roller tube 310. For example, thecap 350 may be removed (e.g., disengaged from the roller tube 310 and/orthe motor drive unit housing) such that the batteries 360 can beaccessed. The battery holder 370 may be configured to be translated(e.g., along the longitudinal axis 316 of the roller tube 310) until atleast a portion is distal from the end 312 of the roller tube 310. Thebattery holder 370 may not fully pull out of the roller tube 310. Stateddifferently, a portion (e.g., an end) of the battery holder 370 mayremain within the cavity 311 of the roller tube 310 when the batteries360 are removed and/or replaced. In this case, one or more of thebatteries 360 may be removed from the battery holder 370 while a portionof the battery holder 370 is retained within the roller tube 310 (e.g.,the cavity 311). Replacement batteries may be installed within thebattery-powered motorized window treatment 300 while the portion of thebattery holder 370 is retained within the roller tube 310.

The battery holder 370 may include a head 372 and an arm 376. The head372 may define an aperture 373 that is configured to receive a nub 363of one of the batteries 360, for example, such that the nub 363 can beelectrically connected to the cap 350. For example, the nub 363 mayextend beyond the head 372 when the batteries 360 are clamped within thebattery holder 370. The battery holder 370 may be electrically connectedto a printed circuit board of the motor drive unit. For example, thebattery holder 370 may be configured to abut a spring (e.g., such asspring 682 shown in FIG. 8A) within the roller tube 310 (e.g., the motordrive unit housing).

FIG. 5A depicts an example battery-powered motorized window treatment500 (e.g., such as the motorized window treatment 100 shown in FIGS. 1Aand 1B, the battery-powered motorized window treatment 200 shown inFIGS. 2A and 2B, the battery-powered motorized window treatment 300shown in FIGS. 3A and 3B, and/or the battery-powered motorized windowtreatment 400 shown in FIGS. 4A and 4B) with a battery holder 570configured to retain the batteries 560. The battery holder 570 may beconfigured to be received in a cavity 511 (e.g., a battery compartment)of the roller tube 510. The battery-powered motorized window treatment500 may include a cap 550 (e.g., such as the cap 250 shown in FIGS. 2Aand 2B) that is configured to retain the batteries 560 and the batteryholder 570 within the roller tube 510. The cap 550 may be removablysecured to the end 512 of the roller tube 510. Alternatively, the cap550 may be removably secured to the motor drive unit housing (e.g., suchas the motor drive unit housing 680 shown in FIG. 8A). The roller tube510 may define a longitudinal axis 516. The longitudinal axis 516 mayextend along a longitudinal direction L.

FIG. 5B is a perspective view of the battery holder 570 without thebatteries 560 installed. The battery holder 570 may define a cylindricalcompartment having a recess 571, an outer surface 572, and an innersurface 574. The cylindrical compartment may define a semi-circularcross-section that extends approximately 180 degrees. The recess 571 maybe configured to receive the batteries 560. For example, the recess 571may retain the batteries 560 within the battery holder 570. For example,the inner surface 574 may abut the batteries 560 when the batteries areinstalled within the battery holder 570. The outer surface 572 may beconfigured to abut an inner surface 513 of the roller tube 510, forexample, when the battery holder 570 is installed within the roller tube510.

The batteries 560 and the battery holder 570 may be configured to beremoved from the cavity 511 along the longitudinal axis 516 of theroller tube 510. For example, the cap 550 may be removed (e.g.,disengaged from the roller tube 510 and/or the motor drive unit housing)such that the batteries 560 and battery holder 570 can be accessed. Thebattery holder 570 may be configured to be translated (e.g., along thelongitudinal axis 516 of the roller tube 510) until it is removed fromthe roller tube 510. The batteries 560 may remain within the batteryholder 570 of the roller tube 510 when the battery holder 570 is removedfrom the cavity 511. The batteries 560 may be removed from the batteryholder 570 when it is removed from the cavity 511. Replacement batteriesmay be installed within the battery holder 570 while it is removed fromthe cavity 511. The battery holder 570 may be open at opposed ends, forexample, such that the batteries 560 can be electrically connected to aprinted circuit board of the motor drive unit. For example, one of thebatteries 560 (e.g., the battery distal from the end 513 of the rollertube 510 when the battery holder 570 is installed within the cavity 511)may be configured to abut a spring (e.g., such as spring 682 shown inFIG. 8A) within the roller tube 510 (e.g., the motor drive unithousing). And, one of the batteries 560 (e.g., the battery proximate tothe end 513 of the roller tube 510 when the battery holder 570 isinstalled within the cavity 511) may be configured to abut an electricalcontact (e.g., the electrical contact 656 shown in FIG. 8A) within thecap 550.

The battery holder 570 may comprise multiple sections 575, which mayeach be configured to hold one of the batteries 560 (e.g., as shown inFIG. 5A). The sections 575 may be connected together via flexibleportions 576 and linking portions 578. For example, the battery holder570 may comprise one flexible portion 576 and two linking portions 578between each pair of adjacent sections 575. The flexible portions 576and the linking portion 578 may extend along the longitudinal axis L ofthe roller tube 510 between the sections 575 of the battery holder 575,such that gaps 579 are formed between the flexible portion 576 and eachrespective linking portion 578. The flexible portions 576 may bearranged towards a lower side of the battery holder 570 (e.g., as shownin FIG. 5B) and the linking portions 578 may be arranged on oppositesides of the recess 571 of the battery holder 570 (e.g., along theradial direction R). The linking portions 578 may be configured to holdthe sections 575 together in rigid connection. For example, the linkingportions 578 may prevent relative movement between the sections 575. Thelinking portions 578 may be configured to be disconnected fromrespective sections 575. The linking portions 578 may be thinner thanthe flexible portions 576, such that the linking portions 578 may be cutby a tool (e.g., wire cutters) to along the flexible portions 576 toflex (e.g., away from the longitudinal axis). When the linking portions578 are disconnected (e.g., cut away) from respective sections 575, theflexible portions 576 may flex, for example, to allow the batteries 560to be removed from the cavity 511 when the mounting bracket 530A islocated near a wall. For example, the flexible portions 576 may beconfigured to bend (e.g., in response to an applied force) to allow thebattery holder 570 to be bent (e.g., curved) while being removed and/orinstalled from/into the roller tube 510. The flexible portions 576 maybe resilient such that the battery holder 570 are linear when theapplied force is removed. For example, the sections 575 may be arrangedlinearly when no force is applied to the battery holder 570.

The battery holder may comprise tabs 573 extending from opposed sides(e.g., along the radial direction R) of each of the sections 575. Thetabs 573 may extend beyond 180 degrees (e.g., the semi-circularcross-section of the battery holder 570). A pair of the tabs 573 in aspecific section 575 may be configured to abut and apply a force to arespective battery of the batteries 560 to retain the respective batterywithin the cavity 571 in the transverse direction T. Each pair of thetabs 573 may be separated (e.g., in the longitudinal direction L) byless than a diameter of the batteries 560 both when no battery isinstalled in a respective section 575 and when a battery is installed inthe respective section 575. The tabs 573 may be configured to be biasedoutward (e.g., flex outward from their resting position) to enable thebatteries 560 to be installed within the battery holder 570 (e.g., thecavity 571). The battery holder 570 may comprise lips 581, 583 atrespective ends of the battery holder 570. The lips 581, 583 may beconfigured to prevent the batteries 560 from translating out of thebattery holder 570 (e.g., the cavity 571) in the longitudinal directionL. For example, the lips 581, 583 may be configured to abut and apply aforce to a respective battery of the batteries 560 to retain thebatteries 560 within the cavity 571 in the longitudinal direction L.

For example, the third portion 5584 may be a batteryholder that is configured to retain the batteries 5560 therein. Thethird portion 5584 may define a trough 5583 (e.g., a batterycompartment) that is configured to receive the batteries 5560. Thetrough 5583 of the third portion 5584 may be defined by a cutout of anupper portion of the motor drive unit housing 5580 (e.g., between thefirst portion 5585 and the second portion 5582). For example, the motordrive unit housing 5580 may include a cutout between the first portion5585 and the second portion 5582 that defines the trough 5583.

The motor drive unit housing 5580 may be configured to be removed (e.g.,at least partially removed) from the roller tube 5510. When the motordrive unit housing 5580 is partially removed from the roller tube 5510,the batteries 5560 may accessible, for example, for replacement. Forexample, a user may adjust the battery-powered motorized windowtreatment 5500 to an extended position (e.g., slid or pivoted position)and may translate the motor drive unit housing 5580 along thelongitudinal axis 5516 such that the third portion 5584 (e.g., thetrough 5583) is external to the roller tube 5510. The batteries 5560 maybe accessible when the third portion 5584 is external to the roller tube5510. The batteries 5560 may rest within the trough 5583 or may beplaced within a battery holder and then installed within the trough5583.

The spring 5586 may extend from the first portion 5585 (e.g., anend 5587) of the motor drive unit housing 5580, for example, into thetrough 5583. The spring 5586 may be configured to abut and apply a forceto one of the batteries 5560, for example, such that the batteries 5560remain in contact with one another while installed within the motordrive unit housing 5580. The spring 5586 may be configured to apply aforce to the batteries 5560 to maintain electrical connection of thebatteries 5560 with the spring 5586 and an electrical contact on thesecond portion 5582 of the motor drive unit housing 5580. The spring5586 may be configured as another electrical contact (e.g., the negativeelectrical contact). The spring 5586 and the electrical contact on thesecond portion 5582 may be electrically connected to the motor drivecircuitry of the motor drive unit 5590 (e.g., a motor drive printedcircuit board of the motor drive unit 5590).

The mounting brackets 5530A, 5530B may be keyed to the respective end5512, 5514 of the roller tube 5510. For example, the motor drive unithousing 5580 may define an outer surface 5581 that may include one ormore splines 5588. The splines 5588 may extend along the length of themotor drive unit housing 5580, for example, from the first portion 5585to the second portion 5582. The splines 5588 (e.g., on the secondportion 5582) may engage with the mounting brackets 5530A, 5530B (e.g.,corresponding features of the mounting brackets 5530A, 5530B). Forexample, the mounting brackets 530A, 530B may define one or more grooves(e.g., as shown in FIGS. 10 and 11) that are configured to receive thesplines 5588. The splines 5588 may be configured to enable the motordrive unit 5590 to torque against one or more of the mounting brackets5530A, 5530B. For example, the motor drive unit 5590 may drive againstone or more of the mounting brackets 5530A, 5530B as the coveringmaterial 5520 is operated between a raised (e.g., open) position and alowered (e.g., closed) position

FIG. 7 depicts the example motorized window treatment 100 in an extendedposition. The mounting bracket 130B may include a sliding portion. Thesliding portion of the mounting bracket 130B may enable a second end 114of the roller tube 110 to be accessible. For example, when the motorizedwindow treatment 100 is in the extended position the second end 114 ofthe roller tube 110 may be further from a window and/or the structure towhich the mounting bracket 130B is anchored than when the motorizedwindow treatment 100 is in an operating position. Stated differently,both mounting brackets 130A, 130B of the motorized window treatment 100may be configured to slide out when the motorized window treatment isoperated to the extended position.

The extended position may define a translated position, for example, asshown in FIG. 7, where both of the mounting brackets 130A, 130B extendsuch that both ends of the roller tube 110 are accessible (e.g., at thesame time).

FIGS. 8A-11 depict an example battery-powered motorized window treatment500 (e.g., such as the motorized window treatment 100 shown in FIGS. 1Aand 1B, the battery-powered motorized window treatment 200 shown inFIGS. 2A and 2B, the battery-powered motorized window treatment 300shown in FIGS. 3A and 3B, the battery-powered motorized window treatment400 shown in FIGS. 4A and 4B, the battery-powered motorized windowtreatment 500 shown in FIG. 5A, and/or the battery-powered motorizedwindow treatment 5500 shown in FIG. 6) in an operating position. Thebattery-powered motorized window treatment 600 may include a roller tube610, a motor drive unit 690, a plurality of batteries 660, and one ormore mounting brackets 630, 631. The operating position may be definedas a position in which the roller tube 610 is supported by and alignedwith both of the mounting brackets 630, 631. The battery-poweredmotorized window treatment 600 may be configured to be operated betweenthe operating position and an extended position, for example, to enableaccess to replace the batteries 660. The extended position may bedefined as a position in which one or more ends of the roller tube 610are accessible while still attached to the mounting brackets 630, 631.The extended position may define a pivoted position, for example, asshown in FIGS. 1B-6, where one of the mounting brackets 630, 631 extendssuch that the batteries 660 are accessible via the end of the rollertube 610. Although not shown in FIGS. 8A-11, the battery-poweredmotorized window treatment 600 may include a flexible material windinglyattached to the roller tube 610 and a hembar that is coupled to a bottomor lower end of the flexible material.

The mounting bracket 630 may be configured to attach the battery-poweredmotorized window treatment 600 to a horizontal structure (e.g., such asa ceiling). The mounting bracket 630 may define a base 638 and an arm632. The base 638 and the arm 632 may define a stationary portion of themounting bracket 630. The mounting bracket 630 may define a translatingportion 634. The translating portion 634 may include an attachmentmember 633 that is configured to receive an end of the roller tube 610and/or a motor drive unit housing 680. The attachment member 633 maydefine an aperture. The base 638 may be configured to attach themounting bracket 630 to a structure. The structure may include a windowframe (e.g., a head jamb or side jambs of a window frame), a wall, aceiling, or other structure, such that the battery-powered motorizedwindow treatment 600 is mounted proximate to an opening (e.g., over theopening or in the opening), such as a window for example. When themounting bracket 630 is attached to a vertical structure, such as awall, the arm 632 of the mounting bracket 630 may extend horizontally(e.g., in the radial direction R) from the base 638.

The translating portion 634 may be configured to translate the rollertube 610 between the operating position (e.g., as shown in FIGS. 12A and12B) and the extended position (e.g., as shown in FIGS. 13A and 13B).The translating portion 634 may be proximate to the base 638 when in theoperating position and distal from the base 638 when in the extendedposition. The end of the roller tube 610 and/or the motor drive unithousing 680 may be accessible via the aperture (e.g., to replace thebatteries 660) when the translating portion 634 is in the extendedposition.

The arm 632 may define one or more features that enable the translatingportion 634 to be translated between the operating position and theextended position while remaining attached thereto. The translatingportion 634 may define one or more corresponding features that areconfigured to cooperate with the one or more features on the arm 632.The arm 632 may define one or more slides 635 (e.g., an upper slide anda lower slide). The slides 635 may protrude from an inner surface of thearm 632. The translating portion 634 may define one or more channels(e.g., an upper channel and a lower channel) that are configured toreceive the slides 635. The translating portion 634 may define a middleslide 636, for example, between the channels. The arm 632 may define achannel (e.g., a middle channel) that is configured to receive themiddle slide 636. The slides 635, 636 and the channels may define anglededges (e.g., tapered edges) such that the attachment of the translatingposition 634 to the arm 632 defines an interlocking slide, e.g., such asa dovetail slide. The translating portion 634 may translate along theslides 635 between the operating position and the extended position. Forexample, the translating portion 634 may translate along the slides 635in the radial direction R.

The mounting bracket 630 may be configured to be secured (e.g., locked)in the operating position and the extended position. The mountingbracket 630 (e.g., the translating portion) may define a locking tab(e.g., such as the locking tab 722 shown in FIGS. 12B and 13B). Inaddition, the mounting bracket 630 may comprise a release button (notshown) that may need to be actuated by a user in order to be releasedthe mounting bracket 630 from the operating position and be moved intothe extended position.

The motor drive unit 690 may include a motor drive printed circuit board692, an intermediate storage device 694, a motor 696, and a gearassembly 698. The intermediate storage device 694 may include one ormore capacitors (e.g., super capacitors) and/or one or more rechargeablebatteries. The intermediate storage device 694 may be configured topower the motor 696 when one or more of the batteries 660 are notinstalled within the roller tube 610, for example, such that positiondata is retained (e.g., on the motor drive printed circuit board 692).The motor drive unit 690 may be operatively coupled to the roller tube610, for example, via a coupler 695 (e.g., a drive coupler). The coupler695 may be an output gear that is driven by the motor 696 and transfersrotation of the motor 696 to the roller tube 610. For example, thecoupler 695 may define a plurality of grooves 697 about its periphery.An inner surface of the roller tube 610 may be splined. That is, theinner surface of the roller tube 610 may define a plurality of splines612. The grooves 697 may be configured to engage respective splines 612such that rotation of the motor 696 is transferred to the roller tube610, for example, via the coupler 695. The motor drive unit 690 may beconfigured to detect when one or more batteries 660 are not installed,for example, when the roller tube 610 is in the operating position. Whenthe motor drive unit 690 detects that one or more batteries 660 are notinstalled and the roller tube 610 is in the operating position, themotor drive unit 690 may prevent rotation of the roller tube 610. Indoing so, the motor drive unit 690 may prevent depletion of theintermediate storage device 694.

The battery-powered motorized window treatment 600 (e.g., the motordrive unit 690) may include an inner bearing 620 and an outer bearing640 that are located external to the roller tube 610. The inner bearing620 and the outer bearing 640 may be non-metallic (e.g., plastic) sleevebearings. The inner bearing 620 and the outer bearing 640 may becaptured between the roller tube 610 and the mounting bracket 630. Theinner bearing 620 may engage the motor drive unit housing 680. The innerbearing 620 may be operatively coupled to the motor drive unit housing680. For example, the inner bearing 620 may define splines (not shown)that are configured to be received by grooves 688 around the peripheryof the motor drive unit housing 680. The inner bearing 620 may be pressfit onto the motor drive unit housing 680. The outer bearing 640 mayengage the roller tube 610. The outer bearing 640 may be operativelycoupled to the roller tube 610. The outer bearing 640 may rotate withthe roller tube 610. The outer bearing 640 may be press fit intoengagement with the roller tube 610. For example, the outer bearing 640may engage the plurality of splines 612 of the roller tube 610. Theinner bearing 620 may remain stationary with the motor drive unithousing 680 as the roller tube 610 rotates. Stated differently, theroller tube 610 and the outer bearing 640 may rotate about the innerbearing 620 and the motor drive unit housing 680.

The batteries 660 may be configured to be removed from the roller tube610, for example, while the motor drive unit housing 680 remains engagedwith the mounting brackets 630. That is, the batteries 660 may beconfigured to be removed from the roller tube 610 when thebattery-powered motorized window treatment 600 is in the pivotedposition. An inside diameter of the inner bearing 620 may be greaterthan an outer diameter of the batteries 660 and/or the battery holder670.

The battery-powered motorized window treatment 600 (e.g., the motordrive unit 690) may include a battery holder 670 and a cap 650. Forexample, the motor drive unit 690 may include the battery holder 670 andthe cap 650. The battery holder 670 and the cap 650 may keep thebatteries 660 fixed in place securely while the batteries 670 areproviding power to the motor drive unit 690 and/or the cap 650. Thebattery holder 670 may be configured to clamp the batteries 660 together(e.g., as shown in FIG. 8A) such that the batteries 660 can be removedfrom the battery-powered motorized window treatment 600 at the same time(e.g., together).

The battery holder 670 may be received in a motor drive unit cavity 689of the motor drive unit 690. The motor drive unit cavity 689 may extendin the longitudinal direction L from an end 681 of the motor drive unit690 (e.g., the motor drive unit housing 680) to an internal wall 683 ofthe motor drive unit 690. The motor drive unit cavity 689 may be open atthe end 681. The motor drive unit 690 may be received within a rollertube cavity 615. The roller tube cavity 615 may be open proximate to anend of the roller tube 610. The roller tube cavity 615 may extend in thelongitudinal direction L along the entire length of the roller tube 610.The cap 650 may be configured to cover the end 681 to the motor driveunit cavity 689. For example, the cap 650 may be received (e.g., atleast partially) within the motor drive unit cavity 689. The cap 650 mayinclude one of more wireless communication components, such as awireless communication circuit (e.g., a control interface printedcircuit board 654) and/or an antenna (e.g., such as the antenna 1545shown in FIG. 29). The wireless communication circuit and/or the antennamay be configured to communicate (e.g., transmit and receive messagesto/from) external control devices via wireless signals, such asradio-frequency (RF) signals. The cap 650 may include a button 652, oneor more wireless communication circuits mounted to the control interfaceprinted circuit board 654, and an electrical contact 656 electricallycoupled to the control interface printed circuit board 654. Theelectrical contact 656 may be a positive electrical contact, forexample, as shown in FIG. 8A. Alternatively, the electrical contact 656may be a negative electrical contact. The cap 650 may include a switch655 (e.g., a mechanical tactile switch) mounted to the control interfaceprinted circuit board 654 and configured to be actuated in response toactuations of the button 652. The button 652 may operate as a light pipe(e.g., may be translucent or transparent), and may be illuminated by anLED (not shown) mounted to the control interface printed circuit board654.

The cap 650 may include a switch or button (e.g., button 154 shown inFIG. 1B) that is configured to disable (e.g., automatically disable)operation of the motor 696 by the motor drive unit 690 when the rollertube 610 is not in the operating position. The switch or button maydisable the operation of the motor 696 of the motor drive unit 690, forexample, when the roller tube 610 is pivoted (e.g., or slid) from theoperating position to the extended position. The switch or button mayenable the operation of the motor 696 when the roller tube 610 reachesthe operating position.

The cap 650 may also comprise a position detect circuit (e.g., such asthe position detect circuit 1546 shown in FIG. 29) for detecting whenthe roller tube 610 is not in the operating position and deactivating(e.g., automatically deactivating) operation of the motor 696 by themotor drive unit 690 (e.g., rather than including the switch or buttonfor deactivating the motor drive unit). For example, the position detectcircuit may comprise a magnetic sensing circuit (e.g., a Hall-effectsensor circuit) configured to detect when the cap 650 is in the extendedposition and not in close proximity to a magnet 675 located inside ofthe arm 632 of the mounting bracket 630. For example, the positiondetect circuit may detect proximity of the cap 650 to the magnet 675.The motor drive unit 690 may disable operation of the motor 696 inresponse to a signal from the position detect circuit such that thecovering material cannot be raised or lowered when the roller tube 610is not in the operating position. The operation of the motor 696 of themotor drive unit 690 may be disabled, for example, when the roller tube610 is pivoted (e.g., or slid) from the operating position to theextended position. The operation of the motor 696 of the drive assembly690 may be enabled in response to the position detect circuit when theroller tube 610 is in the operating position. For example, the positiondetect circuit may also comprise an IR sensor, a switch, and/or thelike.

The batteries 660 may be located between the cap 650 (e.g., the wirelesscommunication circuits of the motor drive unit 690 of thebattery-powered motorized window treatment 600) and a motor driveprinted circuit board 692 of the motor drive unit 690. For example, thewireless communication circuits in the cap 650 may be located at a firstend of the batteries 660 installed in the roller tube 610 and the motordrive unit 690 may be located at an opposed second end of the batteries660.

The wireless communication circuit may be electrically coupled to theantenna within the cap 650. The antenna may be a loop antenna that islocated on (e.g., around a periphery of) the control interface printedcircuit board 654. Alternatively, the antenna may be a monopole. Theantenna may be located proximate to a gap 605 between the bracket 630and the roller tube 610. For example, the antenna may be aligned withthe gap 605. The antenna may transmit and/or receive RF signals throughthe gap 605. The gap 605 includes non-metal components such thatradio-frequency interference and/or shielding is minimized. For example,the battery-powered motorized window treatment 600 may not include metalcomponents at the gap 605. The inner bearing 620 and/or the outerbearing 640 may be disposed within or proximate to the gap 605.

The gap 605 between the roller tube 610 and the bracket 630 may also beconfigured to enable a predetermined tolerance (e.g., angularmisalignment tolerance) between the roller tube 610 and the bracket 630in a pivoted position. For example, when the battery-powered motorizedwindow treatment 600 is in the pivoted position, the gap 605 may enablea portion of the roller tube 610 to be closer to the bracket 630 (e.g.,without contacting the bracket 630) than another portion of the rollertube 610. When the battery-powered motorized window treatment 600 is inthe pivoted position, the gap 605 may be configured such that the rollertube 610 does not abut the bracket 630.

The motor drive unit 690 may include a spring 682, which may extend fromthe internal wall 683 of the motor drive unit 690. The spring 682 may beconfigured to abut and apply a force to one of the batteries 660, forexample, such that the batteries 660 remain in contact with one anotherwhile installed within the motor drive unit cavity 689. The spring 682may be electrically coupled to the motor drive printed circuit board 692via a wire 684. The spring 682 may be a negative electrical contact, forexample, as shown in FIG. 8A. Alternatively, the spring 682 may be apositive electrical contact. The spring 682 may be configured to apply aforce to the batteries 660 to maintain electrical connection of thebatteries 660 with the spring 682 and the electrical contact 656 of thecap 650.

The electrical contact 656 may be electrically connected to the controlinterface printed circuit board 654. The button 652 may be backlit. Forexample, the button 652 may include a light pipe that is illuminated bythe LED within the cap 650 and mounted to the control interface printedcircuit board 654. The button 652 may be configured to enable a user toconfigure (e.g., change one or more settings, associate, etc.) the motordrive unit 690 of the battery-powered motorized window treatment 600.For example the button 652 may enable the user to configure the controlinterface printed circuit board 654 and/or a motor drive printed circuitboard 692. The button 652 may be configured to enable a user to pair thebattery-powered motorized window treatment 600 with a remote controldevice to allow for wireless communication between the remote controldevice and the wireless communication circuit mounted to the controlinterface printed circuit board 654 in the cap 650. The button 652 maybe configured to provide a status indication to a user. For example, thecontrol button 652 may be configured to flash and/or change colors toprovide the status indication to the user. The button 652 may beconfigured to indicate (e.g., via the status indication) whether themotor drive unit 690 is in a programming mode.

The control interface printed circuit board 654 and the motor driveprinted circuit board 692 may be electrically connected. For example,the battery-powered motorized window treatment 600 may include a ribboncable 686. The ribbon cable 686 may be attached to the control interfaceprinted circuit board 654 and the motor drive printed circuit board 692.The ribbon cable 686 may be configured to electrically connect thecontrol interface printed circuit board 654 and the motor drive printedcircuit board 692. The ribbon cable 686 may terminate at the controlinterface printed circuit board 654 and the motor printed circuit board692. For example, the ribbon cable 686 may extend within the cavity 615.The ribbon cable 686 may include electrical conductors for providingpower from the batteries 660 to the control interface printed circuitboard 654 and/or the motor drive printed circuit board 692. The ribboncable 686 may include electrical conductors for conducting controlsignals (e.g., for transmitting one or more messages) between thecontrol interface printed circuit board 654 and the motor drive printedcircuit board 692. For example, the ribbon cable 686 may be configuredto conduct power and/or control signals between the control interfaceprinted circuit board 654 and the motor drive printed circuit board 692.The motor control unit 690 may include a retainer 685 that is configuredto retain the ribbon cable 686 within the motor drive unit cavity 689.For example, the retainer 685 may prevent the ribbon cable 686 frombeing pressed into the motor drive unit cavity 689 when the batteryholder 670 and/or batteries 660 are installed therein. Alternatively,the wireless communication circuits may be mounted to the motor driveprinted circuit board 692 (e.g., rather than the control interfaceprinted circuit board 654), while the antenna may be located on thecontrol interface printed circuit board 654. For example, the antenna onthe control interface printed circuit board 654 may be electricallycoupled to the wireless communication circuits on the motor driveprinted circuit board 692 via a coaxial cable (e.g., which may replacethe ribbon cable 686 and/or be included in addition to the ribbon cable686).

FIGS. 9A, 9B, and 9C depict an idler end of the example battery-poweredmotorized window treatment 600. FIG. 9A is a side view and FIG. 9B is atop view of the idler end of the example battery-powered motorizedwindow treatment 600. FIG. 9C is a perspective view of the idler end ofthe roller tube 610. The mounting bracket 631 (e.g., with the mountingbracket 630) may be configured to attach the battery-powered motorizedwindow treatment 600 to a horizontal structure (e.g., such as aceiling). The mounting bracket 631 may define a base 639 and an arm 637.The mounting bracket 631 may be stationary or may be configured totransition between an operating position and an extended position (e.g.,such as the mounting bracket 630). The arm 637 may include an attachmentmember 619 that is configured to receive an end of the roller tube 610.The arm 637 (e.g., the attachment member 619) may define a cavity 612.The base 639 may be configured to attach the mounting bracket 631 to thestructure. The structure may include a window frame (e.g., a head jambor side jambs of a window frame), a wall, a ceiling, or other structure,such that the battery-powered motorized window treatment 600 is mountedproximate to an opening (e.g., over the opening or in the opening), suchas a window for example. When the mounting bracket 631 is attached to avertical structure, such as a wall, the arm 637 of the mounting bracket631 may extend horizontally (e.g., in the radial direction R) from thebase 639. When the mounting bracket 631 is attached to a horizontalstructure, such as a ceiling, the arm 637 of the mounting bracket 631may extend vertically (e.g., in the transverse direction T) from thebase 639.

The battery-powered motorized window treatment 600 may include an idlerassembly 601. The idler assembly 601 may include an idler shaft 614 andan idler coupler 643. The idler shaft 614 may be configured to supportthe idler end of the battery-powered motorized window treatment 600. Theidler shaft 614 may define an idler arm 613 and an idler base 611. Theidler shaft 614 may be received by the roller tube 610. For example, theidler arm 613 may extend within the roller tube 610 (e.g., the cavity615). For example, the cavity 615 of the roller tube 610 may be open atboth ends. The cavity 615 at the idler end of the battery-poweredmotorized window treatment 600 may be covered by a cover 642. The idlershaft 614 (e.g., the idler arm 613) may extend through the cover 642.The idler shaft 614 (e.g., the idler base 611) may be received (e.g.,captively received) by the cavity 612 in the mounting bracket 631.

The idler shaft 614 (e.g., the idler base 611) may define a pivotsurface 609 that is proximate to the mounting bracket 631, when theidler end of the roller tube is supported by the mounting bracket 631.The pivot surface 609 may be curved to enable the roller tube 610 topivot about its idler end between the operating position and the pivotedposition. For example, the pivot surface 609 may define a convexsurface. The pivot surface 609 may be configured to enable apredetermined tolerance (e.g., angular misalignment tolerance) betweenthe idler base 611 and the cavity 612, for example, when the roller tube610 is in a pivoted position. For example, when the battery-poweredmotorized window treatment 600 is in the pivoted position, the pivotsurface 609 may enable the idler base 611 to remain engaged (e.g.,secured) within the cavity 612 of the mounting bracket 631. Differentportions of the pivot surface 609 may be configured to abut an innersurface 607 of the cavity 612, for example, as the battery-poweredmotorized window treatment 600 is moved between the operating positionand the pivoted position.

The idler base 611 may define a disk portion 691 and an extension 693that extends from the disk portion 691. The pivot surface 609 may belocated on the extension 693. The extension 693 may define edges 623,625 and a tab 699. The tab 699 may be configured to extend in thetransverse direction T beyond an outer perimeter of the disk portion691. The tab 699 may define a curved bottom edge 621. The curved bottomedge 621 may extend between the edges 623, 625. The tab 699 may beconfigured to secure the idler end of the roller tube 610 within themounting bracket 631. For example, the tab 699 may be configured to bereceived within a notch 627 (e.g., such as the notch 934 shown in FIG.16) in the mounting bracket 631 (e.g., in the cavity 612). The notch 627may be located within the cavity 612 distal from the base 639. The tab699 may be configured to prevent unmounting of the roller tube 610 fromthe mounting bracket 631, for example, in the longitudinal direction L.The tab 699 may be configured to rest within the notch 627 when theroller tube 610 is in the operating position, in the pivoted position,and between the operating position and the pivoted position. The notch627 may be configured to prevent movement of the roller tube in thelongitudinal direction L.

The idler shaft 614 may remain stationary as the roller tube 610rotates. The battery-powered motorized window treatment 600 may includeidler bearings 644. The idler bearings 644 may be configured to supportthe roller tube 610 while enabling the roller tube 610 to rotate aboutthe idler shaft 614. The idler bearings 644 may be roller bearings(e.g., such as ball bearings, cylindrical bearings, and/or the like).The idler coupler 643 may be configured to operatively couple the rollertube 610 to the idler bearings 644. For example, the idler coupler 643may be configured to engage (e.g., mesh with) the plurality of splines612 on the roller tube 610 such that the idler coupler 643 rotates withthe roller tube 610. The idler coupler 643 may be configured to transferthe weight of the roller tube 610 to the idler shaft 614.

The battery-powered motorized window treatment 600 may include a springassist assembly 616 (e.g., a torsion spring assembly). The spring assistassembly 616 may include a spring 617 (e.g., a torsion spring), abracket coupling portion 618, and a roller tube coupling portion 608.The bracket coupling portion 618 may be attached to the idler shaft 614(e.g., the idler arm 613) such that the bracket coupling portion 618remains stationary as the roller tube 610 rotates. The roller tubecoupling portion 608 may be operatively coupled to the roller tube 610(e.g., the splines 612) such that the roller tube coupling portion 608rotates with the roller tube 610. The spring 617 may be attached to thebracket coupling portion 618 at one end and to the roller tube couplingportion 608 at the other end. The spring 617 may be configured to coiland uncoil as the roller tube 610 rotates (e.g., depending on thedirection of rotation). For example, the torque applied by the spring617 to the roller tube 610 may change as the roller tube rotates.

The spring assist assembly 616 may be configured to assist the motordrive unit 690 to operate the battery-powered motorized window treatment600. For example, the spring assist assembly 616 may reduce the torquerequired from the motor drive unit 690 to raise and/or lower thecovering material of the battery-powered motorized window treatment 600.The spring assist assembly 616 may prolong the life of the batteries660, for example, by assisting the motor drive unit 690. The springassist assembly 616 may be coupled to the roller tube 610 for providinga constant torque on the roller tube 610 in a direction opposite adirection of the torque provided on the roller tube 610 by the motordrive unit 690. For example, the spring assist assembly 616 may providea torque on the roller tube 610 opposite a torque provided by the motordrive unit 690 to raise the covering material to a positionapproximately midway between the fully-closed and fully-open positionwithout substantial energy being provided by the motor unit 690. Thetorque applied by the spring assist assembly 616 on the roller tube 610may increase as the covering material is lowered. This increasing torqueapplied by the spring assist assembly 616 may balance the increasingtorque created be more of the covering material hanging from the rollertube 610. The balance between the torque applied by the spring assistassembly 616 and the torque applied by the covering material may resultin a substantially constant torque on the motor drive unit 690. Forexample, the spring assist assembly 616 may be configured such that themotor drive unit 690 can operate at a substantially constant torque asthe covering material is raised and lowered (e.g., operated between araised position and a lowered position).

The spring assist assembly 616 may assist the motor drive unit 690 whenraising the covering material above the midway position to thefully-open position, and the spring assist assembly 616 may provide atorque on the drive shaft resisting downward motion of the coveringmaterial when the covering material is lowered from the fully-openposition to the fully-closed position. The motor drive unit 690 mayprovide a torque that is configured to wind up the spring assistassembly 616 when the covering material is lowered from the midwayposition to the fully-closed position.

FIGS. 13A and 13B depict the mountingbracket 700 in an extended position. The mounting bracket 700 may beconfigured to be attached to a structure, e.g., such as a wall or othervertical surface (e.g., as shown in FIGS. 1A-7).

The mounting bracket 700 may be configured to secure, without requiringa tool, a roller tube in a first direction parallel to a longitudinalaxis (e.g., the longitudinal direction L), in a second direction that isparallel to the structure and perpendicular to the longitudinal axis(e.g., the transverse direction T), and in a third directionperpendicular to the structure and the longitudinal axis (e.g., theradial direction R). As shown, the mounting bracket 700 may include astationary portion 710, a translating portion 720, and a sliding portion740.

Thestructure may include a window frame (e.g., a head jamb or side jambs ofa window frame), a wall, a ceiling, or other structure, such that themotorized window treatment is mounted proximate to an opening (e.g.,over the opening or in the opening), such as a window for example. Whenthe mounting bracket 700 is attached to a vertical structure, such as awall, the arm 714 of the mounting bracket 700 may extend horizontally(e.g., in the radial direction R) from the base 712.

The sliding portion 740 may be coupled (e.g., slidably coupled) betweenthe stationary portion 710 and the translating portion 720. Thetranslating portion 720 and the sliding portion 740 may be configured totranslate the roller tube between the operating position (e.g., as shownin FIGS. 12A and 12B) and the extended position (e.g., as shown in FIGS.13A and 13B). The translating portion 720 may be proximate to the base712 when in the operating position and distal from the base 712 when inthe extended position. The end of the roller tube and/or the motor driveunit housing may be accessible via the aperture 732 (e.g., to replacethe batteries) when the translating portion 720 is in the extendedposition.

The stationary portion 710, the translating portion 720, and the slidingportion 740 may define one or more features that enable the translatingportion 720 to be translated between the operating position and theextended position. The translating portion 720 and the sliding portion740 may be configured to move in the radial direction R from theoperating position to the extended position (e.g., in the same directionas the arm 714 extends from the base 712). The translating portion 720may define one or more corresponding features that are configured tocooperate with the one or more features on the sliding portion 740, andthe sliding portion 740 may define one or more corresponding featuresthat are configured to cooperate with the one or more features on thestationary portion 710.

The arm 714 of the stationary portion 710 may define one or more slides(e.g., an upper slide 711 and a lower slide 713). The upper slide 711and the lower slide 713 may protrude from an inner surface 715 of thearm 714. The sliding portion 740 may define one or more channels (e.g.,an upper channel 741 and a lower channel 743). The upper channel 741 maybe configured to receive the upper slide 711 and the lower channel 743may be configured to receive the lower slide 713. The sliding portion740 may translate along the upper slide 711 and the lower slide 713 whenthe translating portion 720 is moving between the operating position andthe extended position. In addition, the sliding portion 740 may defineone or more slides (e.g., a middle slide 749), and the arm 714 maydefine one or more channels (e.g., a middle channel 719). The middleslide 729 may protrude from the sliding portion 740 between the upperchannel 721 and the lower channel 723. The middle channel 719 may belocated between the upper slide 711 and the lower slide 713. The middlechannel 719 may be configured to receive the middle slide 729. Thesliding portion 740 may translate along the middle slide 729 when thetranslating portion 720 is moving between the operating position and theextended position.

The sliding portion 740 may define one or more slides (e.g., an upperslide 742 and a lower slide 744). The upper slide 742 and the lowerslide 744 may protrude from the sliding portion 740. The translatingportion 720 may define one or more channels (e.g., an upper channel 722and a lower channel 724). The upper channel 722 may be configured toreceive the upper slide 742 and the lower channel 724 may be configuredto receive the lower slide 744. The translating portion 720 maytranslate along the upper slide 742 and the lower slide 744 when thetranslating portion 720 is moving between the operating position and theextended position. In addition, the translating portion 720 may defineone or more slides (e.g., a middle slide 727), and the sliding portion740 may define one or more channels (e.g., a middle channel 747). Themiddle slide 727 may protrude from the translating portion 720 betweenthe upper channel 722 and the lower channel 724. The middle channel 747may be located between the upper slide 742 and the lower slide 744. Themiddle channel 747 may be configured to receive the middle slide 727.The translating portion 720 (e.g., the middle channel 747) may translatealong the middle slide 727 when the translating portion 720 is movingbetween the operating position and the extended position.

The mounting bracket 700 may be configured to be secured (e.g., locked)in the operating position and the extended position. The mountingbracket 700 (e.g., the sliding portion 740) may define one or morelocking tabs (e.g., locking tab 745 and locking tab 760). The stationaryportion 710 may define one or more indentations configured to receivethe locking tab 745. For example, the arm 714 may define an operatingposition cavity 762 and an extended position cavity 764. The operatingposition cavity 762 may define a recess (e.g., detent) that receives thelocking tab 745 when the roller tube is in the operating position. Theoperating position cavity 762 may be configured to receive the lockingtab 745 to hold (e.g., lock) the roller tube in the extended position.The extended position cavity 764 may define a recess that receives thelocking tab 745 when the roller tube is in the extended position. Theextended position cavity 764 may be configured to receive the lockingtab 745 to hold (e.g., lock) the roller tube in the extended position.For example, the extended position cavity 764 and the locking tab 745may be configured to prevent the roller tube from sliding out ofengagement with the mounting bracket 700.

The locking tab 745 may be configured to engage the operating positioncavity 762 when the roller tube is in the operating position. Thelocking tab 745 may be configured to engage the extended position cavity764 when the roller tube is in the extended position. For example, thelocking tab 745 (e.g., a distal portion of the locking tab 745) may beconfigured to abut the inner surface 715 of the arm 714 between theoperating position cavity 762 and the extended position cavity 764.Stated differently, the locking tab 745 may slide along the innersurface 715 as the roller tube is operated between the operatingposition and the extended position. The arm 714 (e.g., the inner surface715) may define an inner channel 717 that is configured to receive thelocking tab 745. For example, the locking tab 745 may be received withinand slide along the inner channel 717 as the roller tube is operatedbetween the operating position and the extended position. The innerchannel 717 may be configured to prevent the roller tube from beingpulled out of engagement with the mounting bracket 745 when in theoperating position. For example, the inner channel 717 may define a wall(not shown) distal from the base 712. The wall may be configured toprevent the roller tube from being translated beyond the extendedposition. For example, the locking tab 745 may abut the wall when theroller tube is in the extended position and/or when a radial force isapplied to the roller tube when in the extended position.

The locking tab 760 may be configured to engage an inner surface 734 ofthe translating portion 730. The inner surface 734 may define theaperture 732. The locking tab 760 may be configured to engage thetranslating portion 730 (e.g., the inner surface 734) when the rollertube is in the operating position. The translating portion 730 maydefine one or more indentations configured to receive the locking tab760 as the roller tube is operated between the operating position andthe extended position.

The locking tab 745 and the locking tab 760 may be configured to securethe roller tube in the operating position. The locking tab 745 and thelocking tab 760 may be configured to prevent accidental disengagement ofthe roller tube from the operating position. For example, the lockingtab 745 and the operating position cavity 762 may be configured toresist a first threshold force in the radial direction. In addition, thelocking tab 760 may be configured to resist a second threshold force inthe radial direction. The first threshold force and the second thresholdforce may be the same. When a force greater than the first thresholdforce is applied in the radial direction, the locking tab 745 mayrelease (e.g., disengage) from the operating position cavity 762 suchthat the roller tube can be moved to the extended position. The lockingtab 745 may slide along the inner surface until it reaches the extendedposition cavity 764. For example, the locking tab 745 may be configuredto slide along the inner surface between the operating position cavity762 and the extended position cavity 764. When a force greater than thesecond threshold force is applied in the radial direction, the lockingtab 760 may release (e.g., disengage) from the translating portion 730(e.g., the inner wall 734) such that the roller tube can be moved to theextended position.

The locking tab 745 may be configured to secure the roller tube in theextended position. The locking tab 745 and the extended position cavity764 may provide a positive lock that prevents the roller tube from beingextended beyond the extended position. The locking tab 745 and theextended position cavity 764 may be configured to enable the roller tubeto be released from the extended position and translated back toward theoperating position. The locking tab 745 and the extended position cavity762 may be configured to prevent the roller tube from being pulled outof engagement with the mounting bracket 700, for example, when theroller tube is in the extended position. The mounting bracket 700 mayinclude a release button (not shown) that enables release of thetranslating portion 720 from the operating position such that it can bemoved to the extended position. The mounting bracket 700 may include adisengagement button (e.g., the end portion 1078 shown in FIG. 26A) thatenables disengagement of the translating portion 720 from the stationaryportion 710. For example, operation of the disengagement button maydecouple the translating portion 720 from the stationary portion 710.

The mounting bracket 700 may be used at both sides of a roller tube, forexample, such that the roller tube slides away from the structure. Forexample, the mounting bracket 700 on the opposite end of the roller tubemay be flipped 180 degrees such that the base 712 is also attached tothe structure. Alternatively, the mounting bracket 700 may be used atone end of a roller tube such that the roller tube pivots away from thestructure. The mounting bracket 700 may be configured as an end bracket(e.g., as shown) that receives a single roller tube. Alternatively, themounting bracket 700 may be configured as a center bracket that receivestwo roller tubes. Although the mounting bracket is shown as accepting aroller tube from one side of the arm 714, it should be appreciated thatthe mounting bracket 700 may be configured to accept one roller tube ata first side of the arm 714 and another roller tube at an opposed secondside of the arm 714. The center bracket may define translating portionsand/or sliding portions (e.g., such as the translating portion 720and/or the sliding portion 740) slidably coupled to both sides of thearm 714. The center bracket may define slides (e.g., such as the upperslide 711 and lower slide 713) on both sides of the arm 714. Each of thetranslating portions and/or the sliding portions may slideindependently, for example such that an end of one of the roller tubescan be accessed (e.g., in the extended position) while the other rollertube remains in the operating position.

Whenthe mounting bracket 800 is attached to a horizontal structure, such asa ceiling or a head jamb of a window frame, the arm 814 of the mountingbracket 800 may extend vertically (e.g., in the transverse direction T)from the base 812.

The sliding portion 840 may be coupled (e.g., slidably coupled) betweenthe stationary portion 710 and the translating portion 720. Thetranslating portion 820 may be configured to translate between anoperating position (e.g., as shown in FIGS. 14A and 14B) and an extendedposition (e.g., as shown in FIGS. 15A and 15B). The translating portion820 may be proximate to (e.g., aligned with) the base 812 when in theoperating position and distal from the base 812 when in the extendedposition. The end of the roller tube and/or the motor drive unit housingmay be accessible via the aperture 832 (e.g., to replace the batteries)when the translating portion 820 is in the extended position.

The stationary portion 810, the translating portion 820, and the slidingportion 840 may define one or more features that enable the translatingportion 820 to be translated between the operating position and theextended position. The translating portion 820 and the sliding portion840 may be configured to move in the radial direction R from theoperating position to the extended position (e.g., in a direction thatis 90° from the direction that the arm 814 extends from the base 812).The stationary portion 810 may define a first slide 811. The first slide811 may be configured to engage the sliding portion 840. The slidingportion 840 may define a first channel 842 that is configured to receivethe first slide 811. The translating portion 820 may define one or morecorresponding features that are configured to cooperate with the one ormore features on the stationary portion 810. The first slide 811 mayprotrude from an inner surface 815 of the arm 814. The sliding portion840 may define a second slide 844 that is configured to engage thetranslating portion 820.

For example, the first locking tab on theslide may be configured to abut the inner surface 815 of the arm 814between the operating position arm cavity and the extended position armcavity. Stated differently, the first locking tab may slide along theinner surface 815 as the roller tube is operated between the operatingposition and the extended position.

The first and second locking tabs may be configured to secure the rollertube in the operating position.

Alternatively, the mounting bracket 1000 may be usedat one end of a roller tube such that the roller tube pivots away fromthe structure. The mounting bracket 1000 may be configured as an endbracket (e.g., as shown) that receives a single roller tube.Alternatively, the mounting bracket 1000 may be configured as a centerbracket that receives two roller tubes. Although the mounting bracket1000 is shown as accepting a roller tube from one side of the arm 1014,it should be appreciated that the mounting bracket 1000 may beconfigured to accept one roller tube at a first side of the arm 1014 andanother roller tube at an opposed second side of the arm 1014. Thecenter bracket may define translating portions and/or sliding portions(e.g., such as translating portion 1020 and/or the sliding portion 1040)on both sides of the arm 1014. The center bracket may define slides(e.g., such as upper slide 1011 and lower slide 1013) on both sides ofthe arm 1014. Each of the translating portions and/or sliding portionsmay slide independently, for example such that an end of one of theroller tubes can be accessed (e.g., in the extended position) while theother roller tube remains in the operating position.

The stationary portion 1210, the translating portion 1220, and thesliding portion 1240 may define one or more features that enable thetranslating portion 1220 to be translated between the operating positionand the extended position. The translating portion 1220 may beconfigured to move in the radial direction R from the operating positionto the extended position (e.g., in the same direction as the frontportion 1214 extends from the rear portion 1212). The translatingportion 1220 may define one or more corresponding features that areconfigured to cooperate with the one or more features on the slidingportion 1240, and the sliding portion 1240 may define one or morecorresponding features that are configured to cooperate with the one ormore features on the stationary portion 1210.

The stationary portion 1210 may define one or more slides (e.g., anupper slide 1211 and a lower slide 1213). The upper slide 1211 and thelower slide 1213 may protrude from an inner surface 1215 of thestationary portion 1210. The sliding portion 1240 may define one or morechannels (e.g., an upper channel 1241 and a lower channel 1243). Theupper channel 1241 may be configured to receive the upper slide 1211 andthe lower channel 1243 may be configured to receive the lower slide1213. The sliding portion 1240 may translate along the upper slide 1211and the lower slide 1213 when the translating portion 1220 is movingbetween the operating position and the extended position. In addition,the sliding portion 1240 may define one or more slides (e.g., a middleslide 1249), and the stationary portion 1210 may define one or morechannels (e.g., a middle channel 1219). The middle slide 1229 mayprotrude from the sliding portion 1240 between the upper channel 1221and the lower channel 1223. The middle channel 1219 may be locatedbetween the upper slide 1211 and the lower slide 1213. The middlechannel 1219 may be configured to receive the middle slide 1229. Thesliding portion 1240 may translate along the middle slide 1229 when thetranslating portion 1220 is moving between the operating position andthe extended position.

The sliding portion 1240 may define one or more slides (e.g., an upperslide 1242 and a lower slide 1244). The upper slide 1242 and the lowerslide 1244 may protrude from the sliding portion 1240. The translatingportion 1220 may define one or more channels (e.g., an upper channel1222 and a lower channel 1224). The upper channel 1222 may be configuredto receive the upper slide 1242 and the lower channel 1224 may beconfigured to receive the lower slide 1244. The translating portion 1220may translate along the upper slide 1242 and the lower slide 1244 whenthe translating portion 1220 is moving between the operating positionand the extended position. In addition, the translating portion 1220 maydefine one or more slides (e.g., a middle slide 1227), and the slidingportion 1240 may define one or more channels (e.g., a middle channel1247). The middle slide 1227 may protrude from the translating portion1220 between the upper channel 1222 and the lower channel 1224. Themiddle channel 1247 may be located between the upper slide 1242 and thelower slide 1244. The middle channel 1247 may be configured to receivethe middle slide 1227. The translating portion 1220 may translate alongthe middle slide 1227 when the translating portion 1247 is movingbetween the operating position and the extended position.

The mounting bracket 1200 may be configured to be secured (e.g., locked)in the operating position and the extended position. The mountingbracket 1200 (e.g., the sliding portion 1240) may define a first lockingtab 1260 and a second locking tab 1265. The stationary portion 1210 andthe translating portion 1220 may each define one or more indentationsconfigured to receive the first locking tab 1260. For example, thestationary portion 1210 may define an operating position cavity 1262 andan extended position cavity 1264, and the translating portion 1220 maydefine an operating position cavity 1266 and an extended position cavity1268. The operating position cavity 1262 of the stationary portion 1210and the operating position cavity 1266 of the translating portion 1220may each define a recess (e.g., detent) that is configured to receivethe first locking tab 1260 and the second locking tab 1265,respectively, when the roller tube is in the operating position. Theextended position cavity 1264 of the stationary portion 1210 and theextended position cavity 1268 of the translating portion 1220 may eachdefine a recess (e.g., detent) that is configured to receive the firstlocking tab 1260 and the second locking tab 1265, respectively, when theroller tube is in the extended position. The operating position cavity1262 of the stationary portion 1210 and the operating position cavity1266 of the translating portion 1220 may be configured to receive therespective locking tabs 1260, 1265 to hold (e.g., lock) the roller tubein the operating position. The extended position cavity 1264 of thestationary portion 1210 and the extended position cavity 1268 of thetranslating portion 1220 may be configured to receive the respectivelocking tabs 1260, 1265 to hold (e.g., lock) the roller tube in theextended position. For example, the extended position cavities 1264,1268 and the respective locking tabs 1260, 1265 may be configured toprevent the roller tube from sliding out of engagement with the mountingbracket 1200.

The first and second locking tabs 1260, 1265 may be configured to engagethe respective operating position cavities 1262, 1266 when the rollertube is in the operating position. The first and second locking tab1260, 1265 may be configured to engage the respective extended positioncavities 1264, 1268 when the roller tube is in the extended position.For example, the first and second locking tab 1260, 1265 (e.g., a distalportion of the locking tabs) may be configured to be received in (e.g.,and slide along) an inner channel 1216 in the stationary portion 1210and an inner channel 1226 in the translating portion 1220, respectively,as the mounting bracket 1200 is transitioned between the operatingposition and the extended position. The inner channels 1216, 1226 may beconfigured to prevent the roller tube from being pulled out ofengagement with the mounting bracket 1200. For example, the innerchannels 1216, 1226 may define respective walls 1218, 1228 configured toabut the respective locking tabs 1260, 1265 to prevent the roller tubefrom being translated beyond the extended position.

The first and second locking tabs 1260, 1265 may be configured to securethe roller tube in the operating position. The first and second lockingtabs 1260, 1265 may be configured to prevent accidental disengagement ofthe roller tube from the operating position. For example, the firstlocking tab 1260 and the operating position cavity 1262 of thestationary portion 1210 may be configured to resist a threshold force inthe radial direction, and the second locking tab 1265 and the operatingposition cavity 1266 of the translating portion 1220 may be configuredto resist a threshold force in the opposing radial direction. When aforce greater than the threshold force is applied in the radialdirection and the opposing radial direction, the first and secondlocking tabs 1260, 1265 may release (e.g., disengage) from the operatingposition cavities 1262, 1266, respectively, such that the roller tubecan be moved to the extended position. The first and second locking tabs1260, 1265 may slide through the respective inner channels 1216, 1226until reaching the respective extended position cavity 1264, 1268.

The first and second locking tabs 1260, 1265 may be configured to securethe roller tube in the extended position. The walls 1218, 1228 of therespective channels 1216, 1226 may provide a positive lock with therespective locking tabs 1260, 1265 to prevent the roller tube from beingextended beyond the extended position. For example, the locking tabs1260, 1265 may abut the respective walls 1218, 1228 when the roller tubeis in the extended position and/or when a radial force is applied to theroller tube when in the extended position. The first and second lockingtabs 1260, 1265 and the respective extended position cavities 1264, 1268may be configured to enable the roller tube to be released from theextended position and translated back toward the operating position. Thefirst and second locking tabs 1260, 1265 and the respective extendedposition cavities 1264, 1268 may be configured to prevent the rollertube from being pulled out of engagement with the mounting bracket 1200,for example, when the roller tube is in the extended position. Themounting bracket 1200 may include a release button (not shown) thatenables release of the translating portion 1220 and/or the slidingportion 1240 from the operating position such that the mounting bracket1200 can be translated to the extended position. The mounting bracket1200 may include a disengagement button (not shown) that enablesdisengagement of the translating portion 1220 and/or the sliding portion1240 from the stationary portion 1210.

The mounting bracket 1200 may be used at both sides of a roller tube,for example, such that the roller tube slides away from the structure.For example, the mounting bracket 1200 on the opposite end of the rollertube may be flipped 180 degrees. Alternatively, the mounting bracket1200 may be used at one end of a roller tube such that the roller tubepivots away from the structure. The mounting bracket 1200 may beconfigured as an end bracket (e.g., as shown) that receives a singleroller tube.

FIG. 26A depicts an example mounting bracket 1000′ for use with abattery-powered motorized window treatment (e.g., such as the motorizedwindow treatment 100 shown in FIGS. 1A and 1B, the battery-poweredmotorized window treatment 200 shown in FIGS. 2A and 2B, thebattery-powered motorized window treatment 300 shown in FIGS. 3A and 3B,the battery-powered motorized window treatment 400 shown in FIGS. 4A and4B, the battery-powered motorized window treatment 500 shown in FIG. 5A,the battery-powered motorized window treatment 5500 shown in FIG. 6,and/or the battery-powered motorized window treatment 600 shown in FIGS.8A-11) in an operating position. The mounting bracket 1000′ may beconfigured to be attached to a structure, e.g., such as a wall or othervertical surface (e.g., as shown in FIGS. 1A-7). The mounting bracket1000′ may be an alternate version of the mounting bracket 1000 shown inFIGS. 17A-19B, and may have many of the same features and elements.

The mounting bracket 1000′ shown in FIG. 26A may comprise a locking tab1070 (e.g., rather than the first locking tab 1060 shown in FIGS. 18B,19A, and 19B) that may allow for releasable attachment of the stationaryportion 1010 to the translating portion 1020 and the stationary portion1040. The locking tab 1070 may be located in the middle channel 1047 ofthe sliding portion 1040. The locking tab 1070 may be received in theoperating position cavity 1062 of the stationary portion 1010 when theroller tube is in the operating position, and received in the extendedposition cavity 1064 of the stationary portion 1010 when the roller tubeis in the extended position. The operating position cavity 1062 and theextended position cavity 1064 may be configured to receive the lockingtab 1070 to hold the roller tube in the operating position and theextended position, respectively.

As shown in FIG. 26A, the locking tab 1070 may comprise an arm 1072 thatextends into an opening 1074 in the middle channel 1074 of the slidingportion 1040. The arm 1072 of the locking tab 1070 may define a distalportion 1075 of the locking tab 1070) that may be received in (e.g., andslide along) the inner channel 1016 in the stationary portion 1010 asthe mounting bracket 1000′ is transitioned between the operatingposition and the extended position. The distal portion 1075 of thelocking tab 1070 may abut the wall 1018 of the inner channel 1016 whenthe mounting bracket 1000′ is in the extended position to prevent theroller tube from being pulled out of engagement with the mountingbracket 1000′.

The opening 1074 may be formed between opposing extensions 1076 thatextend towards an end portion 1078 of the middle channel 1074. The endportion 1078 may be spaced apart from the adjacent structure of thesliding portion 1040 by a gap 1079 (e.g., not connected to the upperslide 1042 and the lower slide 1044). The end portion 1078 may beconfigured to disengage the sliding portion 1040 and/or the translatingportion 1020 from the stationary portion 1010. When the end portion 1078is depressed by a user, the extensions 1076 may flex to allow the endportion 1078 to move into the inner channel 1016 of the stationaryportion 1010 and allow the distal portion 1075 of the arm 1072 todisengage with the wall 1018 of the middle channel 1016, thus allowingthe translating portion 1020 and the sliding portion 1040 to bedisengaged from the stationary portion 1010 of the mounting bracket1000′. For example, the user may depress the end portion 1078 to adjustthe roller tube from the operating position to the extended position.The user may also depress the end portion 1078 to adjust the roller tubefrom the extended position to the operating position.

The mounting bracket 1000′ may be used to mount the battery-poweredmotorized window treatment to the structure. For example, the stationaryportion 1010 of the mounting bracket 1000′ may be mounted to thestructure. An idler bracket (e.g., the mounting bracket 631 shown inFIGS. 9A, 9B, the mounting bracket 1330 shown in FIG. 27B, 27C and/orthe mounting bracket 1430 shown in FIGS. 28B-28D) may be mounted to thestructure. An idler end of a roller tube (e.g., roller tube 110, 210,310, 410, 510, 5510, 610, 1310, 1410) of the battery-powered motorizedwindow treatment may be inserted into the idler bracket. The translatingportion 1020 of the mounting bracket 1000′ may be attached to a motorend of the roller tube. The sliding portion 1040 may be connected to thetranslating portion 1020. The sliding portion 1040 may be inserted intothe stationary portion 1010 of the mounting bracket 1000′ until theroller tube is in the operating position. For example, the roller tubemay be pivoted as the idler end remains attached to the idler bracket toinsert the sliding portion 1040 within the stationary portion 1010.Although mounting of the battery-powered motorized window treatment tothe structure is described with respect to the mounting bracket 1000′,it should be appreciated that the battery-powered motorized windowtreatment may be similarly mounted to the structure using any of theother mounting brackets (e.g., mounting brackets 130A, 130B, 230A, 330A,430A, 530A, 5530A, 630, 700, 800, 900, 1000, 1100, 1200) describedherein having a stationary portion, a sliding portion, and a translatingportion.

It should be appreciated that the locking tab 1070 shown in FIG. 26A mayalso be used in any of the other mounting brackets shown and describedherein (e.g., mounting brackets 130A, 130B, 230A, 330A, 430A, 530A,5530A, 630, 700, 800, 900, 1000, 1100, 1200) having a stationaryportion, a sliding portion, and a translating portion.

FIGS. 26B and 26C depict an example mounting bracket 1000″ for use witha battery-powered motorized window treatment (e.g., such as themotorized window treatment 100 shown in FIGS. 1A and 1B, thebattery-powered motorized window treatment 200 shown in FIGS. 2A and 2B,the battery-powered motorized window treatment 300 shown in FIGS. 3A and3B, the battery-powered motorized window treatment 400 shown in FIGS. 4Aand 4B, the battery-powered motorized window treatment 500 shown in FIG.5A, the battery-powered motorized window treatment 5500 shown in FIG. 6,and/or the battery-powered motorized window treatment 600 shown in FIGS.8A-11) in an operating position (e.g., shown in FIG. 26B) and anextended position (e.g., shown in FIG. 26C). The mounting bracket 1000″may be configured to be attached to a structure, e.g., such as a wall orother vertical surface (e.g., as shown in FIGS. 1A-7).

The mounting bracket1330 may be configured (e.g., with one or more other mounting brackets)to attach the battery-powered motorized window treatment 1300 to astructure. For example, mounting bracket 1300 may be configured to beattached to a wall or other vertical structure (e.g., as shown in FIGS.1A-7), and/or may be configured to be attached to a ceiling, a head jambof a window frame, or other horizontal structure (e.g., as shown inFIGS. 8A, 8B, and 9).

The mounting bracket 1300 may be configured to secure, without requiringa tool, the roller tube 1310 in a first direction parallel to alongitudinal axis (e.g., the longitudinal direction L), in a seconddirection that is parallel to the structure and perpendicular to thelongitudinal axis (e.g., the transverse direction T), and in a thirddirection perpendicular to the structure and the longitudinal axis(e.g., the radial direction R). The mounting bracket 1330 may define abase 1331 (e.g., a foot), an arm 1332. The arm 1332 may include anattachment member 1333 that is configured to receive the idler end ofthe roller tube 1310. The arm 1332 (e.g., the attachment member 1333) ofthe mounting bracket 1330 may define a cavity 1334.

The base 1331 may be configured to attach the mounting bracket 1330 tothe structure. The structure may include a window frame (e.g., a headjamb or side jambs of a window frame), a wall, a ceiling, or otherstructure, such that the battery-powered motorized window treatment 1300is mounted proximate to an opening (e.g., over the opening or in theopening), such as a window for example. When the mounting bracket 1330is attached to a vertical structure, such as a wall, the arm 1332 of themounting bracket 1330 may extend horizontally (e.g., in the radialdirection R) from the base 1331. When the mounting bracket 1330 isattached to a horizontal structure, such as a ceiling, the arm 1332 ofthe mounting bracket 1330 may extend vertically (e.g., in the transversedirection T) from the base 1331. A base cover (e.g., such as the basecover 916 shown in FIG. 16) may be configured to be detachably mountedover the base 1331 of the mounting bracket 1330. The base cover may beconfigured to cover and/or conceal the base 1331.

The battery-powered motorized window treatment 1300 may include an idlershaft 1314 and an idler coupler 1343. The idler shaft 1314 may beconfigured to support the idler end of the battery-powered motorizedwindow treatment 1300. The idler shaft 1314 may define an idler base1311 and an idler arm 1313. The idler shaft 1314 may be received by theroller tube 1310. For example, the idler arm 1313 may extend within theroller tube 1310. For example, the idler arm 1313 may be configured tobe received within a cavity 1315 of the roller tube 1310. The cavity1315 at the idler end of the battery-powered motorized window treatment1300 may be covered by a cover 1342. The idler shaft 1314 (e.g., theidler arm 1313) may extend through the cover 1342. The idler shaft 1314(e.g., the idler base 1311) may be received (e.g., captively received)by the cavity 1334 in the mounting bracket 1330.

The idler shaft 1314 may define a tapered portion 1316 between the idlerarm 1313 and the idler base 1311. The tapered portion 1316 may have adiameter that is less than a diameter of the idler base 1311 and adiameter of the idler arm 1313. The tapered portion 1316 may beconfigured to enable the battery-powered motorized window treatment 1300to be pivoted to the pivoted position. For example, the cavity 1334 maydefine a chamfered portion 1335. The chamfered portion 1335 may define achamfered edge proximate to (e.g., at) an inner surface 1336 of theattachment member 1333. The chamfered portion 1335 may be configured toprovide clearance (e.g., approximately 10 degrees) for the idler shaft1314 as the battery-powered motorized window treatment 1300 is operatedbetween the pivoted position and the operating position. For example,the chamfered portion 1335 may be configured to prevent the idler shaft1314 from contacting the attachment member 1333 of the mounting bracket1330 when the battery-powered motorized window treatment 1300 is in thepivoted position. The cavity 1330 (e.g., the chamfered portion 1335) maybe configured to guide the idler base 1311 into the cavity 1334. Itshould be appreciated that the chamfered portion 1335 may bealternatively shaped. For example, the chamfered portion 1335 may bebeveled, filleted, and/or the like.

The idler base 1311 may define a polygon-shaped (e.g., octagonal-shaped)ball with a plurality of faces 1318. Each of the plurality of faces 1318may be curved along the longitudinal direction L, for example, toprovide angular compliance between the idler shaft 1314 and the mountingbracket 1330. For example, the idler base 1311 may enable angularmisalignment with the cavity 1334 in the transverse direction T and/orthe radial direction R. The cavity 1334 may define a polygon-shaped(e.g., octagonal-shaped) cross-section with a plurality of walls 1337.Each of the plurality of walls 1337 may define a side of the polygonformed by the cross section of the cavity 1334. Each of the plurality ofwalls 1337 may correspond to adjacent faces of the idler base 1311. Eachof the plurality of faces 1318 may be identical (e.g., have the samedimensions). When the idler base 1311 is fully inserted into the cavity1334, two of the faces 1318 may be aligned with (e.g., substantiallyparallel to) and abut the walls 1337 of the cavity 1334. Abutment of twoor more of the faces 1318 against respective walls 1337 of the cavity1334 may prevent rotation of the idler base 1311 as the roller tube 1310rotates. The idler base 1311 and the cavity 1334 may define a balljoint. The chamfered portion 1335 may define sections that correspond tothe plurality of walls 1337. For example, the chamfered portion 1335 maydefine a plurality of evenly shaped sections that correspond to theplurality of walls 1337. It should be appreciated that although thechamfered portion 1335 is shown separated into sections in FIG. 27A, thechamfered portion 1335 may alternatively be configured as a continuouschamfer about the cavity 1334.

The idler base 1311 may define a pivot surface 1309 located distal fromthe idler arm 1313. The pivot surface 1309 may be proximate to the innerwall 1336 of the cavity 1334 when the idler end of the roller tube 1310is supported by the mounting bracket 1330. The pivot surface 1309 may beflat or curved to enable the roller tube 1310 to pivot about its idlerend between the operating position and the pivoted position. The pivotsurface 1309 may be configured to abut an inner wall 1338 of the cavity1334, for example, when the roller idler base 1311 is fully insertedinto the cavity 1334. The idler base 1311 and the cavity 1330 may beconfigured to enable a predetermined tolerance (e.g., angularmisalignment tolerance) between the roller tube 1310 and the mountingbracket 1330, for example, when the roller tube 1310 is in a pivotedposition.

The mounting bracket 1330 may define a slot 1320 that is configured toreceive a retaining clip 1325. The slot 1320 may be located within thecavity 1334, for example, between the chamfered portion 1335 and theinner wall 1336 of the cavity 1330. The slot 1320 may extend from thecavity 1330 into the mounting bracket 1330 in a direction along a planedefined by the transverse direction T and the radial direction R (e.g.,wherein the longitudinal axis is normal to the plane defined by thetransverse direction T and the radial direction R). The retaining clip1325 may be configured to secure the idler base 1311 within the cavity1334 (e.g., retain and prevent accidental disengagement of the rollertube 1310 from the mounting bracket 1300). For example, the retainingclip 1325 may couple the idler base 1311 to the mounting bracket 1330.The retaining clip 1325 may be configured to abut the idler base 1311,for example, to prevent unmounting of the idler base 1311 from themounting bracket 1330. Stated differently, the retaining clip 1325 maybe configured to prevent unmounting of the roller tube 1310 from themounting bracket 1330, for example, in the longitudinal direction, L.For example, the retaining clip 1325 may be placed within the slot 1320before the idler base 1311 is moved within the cavity 1334. Theretaining clip 1325 may be configured to extend radially as the idlerbase 1311 is pressed into the cavity 1334. The retaining clip 1325 mayreturn to its normal shape when the idler base 1311 is fully installedwithin the cavity 1334. For example, the retaining clip 1325 may flex toaccept the idler base 1311 and provide positive feedback (e.g., to aninstaller) that the idler base 1311 is fully installed within the cavity1334.

The idler shaft 1314 may remain stationary as the roller tube 1310rotates. The battery-powered motorized window treatment 1300 may includeidler bearings 1344. The idler bearings 1344 may be configured tosupport the roller tube 1310 while enabling the roller tube 1310 torotate about the idler shaft 1314. The idler bearings 1344 may be rollerbearings (e.g., such as ball bearings, cylindrical bearings, and/or thelike). The idler coupler 1343 may be configured to operatively couplethe roller tube 1310 to the idler bearings 1344. For example, the idlercoupler 1343 may be configured to engage (e.g., mesh with) the rollertube 1310 such that the idler coupler 1343 rotates with the roller tube1310. The idler coupler 1343 may be configured to transfer the weight ofthe roller tube 1310 to the idler shaft 1314. The idler shaft 1314 maybe configured to transfer the weight of the roller tube 1310 to themounting bracket 1331.

The mounting bracket 1330 may be configured as an end bracket (e.g., asshown) that receives a single roller tube. Alternatively, the mountingbracket 1330 may be configured as a center bracket that receives tworoller tubes. Although the mounting bracket 1330 is shown as accepting aroller tube from one side of the arm 1332, it should be appreciated thatthe mounting bracket 1330 may be configured to accept one roller tube ata first side of the arm 1332 and another roller tube at an opposedsecond side of the arm 1332.

While the mounting bracket 1330 shown and described herein has acircular profile and attachment member 1333, the mounting bracket 1330may also have a differently-shaped profile and/or attachment member. Forexample, the mounting bracket 1330 may have a profile and/or attachmentmember of another shape, such as, for example, a rectangular shape, asquare shape, a triangular shape, an oval shape, or any suitable shape.In addition, the side surfaces of the mounting bracket 1330 may havedifferent shapes and may be planar or non-planar. Further, the surfacesof the mounting bracket 1330 may be characterized by various colors,finishes, designs, patterns, etc.

It should be appreciated that the retaining clip 1325 may be a retainingring (e.g., such as the retaining ring 1422 shown in FIGS. 28A and 28C).For example, the retaining clip 1325 may comprise an o-ring and may havea circular-shaped cross-section. The retaining clip 1325 may be placedwithin the slot 1320 before the idler base 1311 is moved within thecavity 1334. The retaining clip 1325 may be configured to be deformed asthe idler base 1311 is pressed into the cavity 1334. The retaining clip1325 may return to its normal shape when the idler base 1311 is fullyinstalled within the cavity 1334 and may prevent the unmounting of theroller tube 1310 from the mounting bracket 1330.

FIG. 28A is a perspective view of the idler end of a roller tube1410 of the battery-powered motorized window treatment 1400. FIG. 28B isa perspective view of an example mounting bracket 1430 configured toreceive the idler end of the roller tube 1410 shown in FIG. 28A. FIG.28C is a front cross-section view of the idler end of the examplebattery-powered motorized window treatment 1400. The mounting bracket1430 may be configured (e.g., with one or more other mounting brackets)to attach the battery-powered motorized window treatment 1400 to astructure. For example, mounting bracket 1400 may be configured to beattached to a wall or other vertical structure (e.g., as shown in FIGS.1A-7), and/or may be configured to be attached to a ceiling, a head jambof a window frame, or other horizontal structure (e.g., as shown inFIGS. 8A, 8B, and 9).

The mounting bracket 1400 may be configured to secure, without requiringa tool, a roller tube in a first direction parallel to a longitudinalaxis (e.g., the longitudinal direction L), in a second direction that isparallel to the structure and perpendicular to the longitudinal axis(e.g., the transverse direction T), and in a third directionperpendicular to the structure and the longitudinal axis (e.g., theradial direction R). The mounting bracket 1430 may define a base 1431(e.g., a foot), an arm 1432. The arm 1432 may include an attachmentmember 1433 that is configured to receive the idler end of the rollertube 1410.

The idler shaft 1414 may be received by theroller tube 1410. For example, the idler arm 1413 may extend within theroller tube 1410. For example, the idler arm 1413 may be configured tobe received within a cavity 1415 of the roller tube 1410. The cavity1415 at the idler end of the battery-powered motorized window treatment1400 may be covered by a cover 1442. The idler shaft 1414 (e.g., theidler arm 1413) may extend through the cover 1442. The idler shaft 1414(e.g., the idler base 1411) may be received (e.g., captively received)by the cavity 1434 in the mounting bracket 1430.

The idler shaft 1414 may define a tapered portion 1416 between the idlerarm 1413 and the idler base 1411. The tapered portion 1416 may have adiameter that is less than a diameter of the idler base 1411 and adiameter of the idler arm 1413. The tapered portion 1416 may beconfigured to enable the battery-powered motorized window treatment 1400to be pivoted to the pivoted position. For example, the cavity 1434 maydefine a chamfered portion 1435. The chamfered portion 1435 may define achamfered edge proximate to (e.g., at) an inner surface 1436 of theattachment member 1433. The chamfered portion 1435 may be configured toprovide clearance (e.g., approximately 10 degrees) for the idler shaft1414 as the battery-powered motorized window treatment 1400 is operatedbetween the pivoted position and the operating position. For example,the chamfered portion 1435 may be configured to prevent the idler shaft1414 from contacting the attachment member 1433 of the mounting bracket1430 when the battery-powered motorized window treatment 1400 is in thepivoted position.

The idler base 1411 may define a polygon-shaped (e.g., square-shaped)with a plurality of faces 1418 (e.g., four). The idler base 1411 maydefine radius edges 1417 between each of the plurality of faces 1418.Each of the plurality of faces 1418 may be curved, for example, toprovide angular compliance between the idler shaft 1414 and the mountingbracket 1430. For example, the idler base 1411 may enable angularmisalignment with the cavity 1434 in the transverse direction T and/orthe radial direction R. The cavity 1434 may define a polygon-shaped(e.g., square-shaped) cross-section with a plurality of walls 1437.

When the idler base 1411 is fully inserted into the cavity1434, two of the faces 1418 may be aligned with (e.g., substantiallyparallel to) and abut the walls 1437 of the cavity 1434. The idler base1411 and the cavity 1434 may define a ball joint. The chamfered portion1435 may define sections that correspond to the plurality of walls 1437.For example, the chamfered portion 1435 may define a plurality of evenlyshaped sections that correspond to the plurality of walls 1437. Itshould be appreciated that although the chamfered portion 1435 is shownseparated into sections in FIG. 28A, the chamfered portion 1435 mayalternatively be configured as a continuous chamfer about the cavity1434.

The idler base 1411 may define a pivot surface 1409 located distal fromthe idler arm 1413. The pivot surface 1409 may be proximate to the innerwall 1436 of the cavity 1434 when the idler end of the roller tube 1410is supported by the mounting bracket 1430.

The idler shaft 1414 may define a groove 1420 that is configured toreceive a retaining ring 1422. The groove 1420 may be located within theidler base 1411, for example, between the tapered portion 1416 and thepivot surface 1409. The groove 1420 may extend in a plane defined by thetransverse direction T and the radial direction R (e.g., wherein thelongitudinal axis is normal to the plane defined by the transversedirection T and the radial direction R). The retaining ring 1422 may beconfigured to secure the idler base 1411 within the cavity 1434 (e.g.,retain and prevent accidental disengagement of the roller tube 1410 fromthe mounting bracket 1400). For example, the retaining ring 1422 maycouple the idler base 1411 to the mounting bracket 1430.

Stated differently, the retaining ring 1422 may be configured toprevent unmounting of the roller tube 1410 from the mounting bracket1430, for example, in the longitudinal direction, L. For example, theretaining ring 1422 may comprise an o-ring. The retaining ring 1422 mayhave a circular-shaped cross-section as shown in FIG. 28C. It should beappreciated that the retaining ring 1422 may have a differently shapedcross-section.

The retaining ring 1422 may beconfigured to be located in the recess 1423 of the cavity 1434 after theidler base 1411 is inserted into the cavity 1434. For example, therecess 1423 may be configured to partially receive the retaining ring1422 when the idler base 1411 is received within the cavity 1434. Theretaining ring 1422 may return to its normal shape when the idler base1411 is fully installed within the cavity 1434. For example, whiledeforming to accept the idler base 1411, the retaining ring 1422 mayprovide positive feedback (e.g., to an installer) that the idler base1411 is fully installed within the cavity 1434.

The idler shaft 1414 may remain stationary as the roller tube 1410rotates. The battery-powered motorized window treatment 1400 may includeidler bearings 1444.

The retaining ring 1422 mayreturn to its normal shape when the idler base 1411 is fully installedwithin the cavity 1434. Alternatively, the retaining ring 1422 may beextended radially and/or may be compressed between the idler base 1411and the cavity 1434 when the idler base 1411 is fully installed withinthe cavity 1434. The retaining ring 1422 may be received within thegroove 1420 when the idler base 1411 is fully installed within thecavity 1434. For example, the retaining ring 1422 may flex to accept theidler base 1411 and provide positive feedback (e.g., to an installer)that the idler base 1411 is fully installed within the cavity 1434.

FIG. 28 is a block diagram of an example motor drive unit 1500 (e.g.,the motor drive unit 5590 shown in FIG. 6 and/or the motor drive unit690 of the motorized window treatment 600 shown in FIGS. 8A, 8B, and 9)of a battery-powered motorized window treatment (e.g., such as themotorized window treatment 100 shown in FIGS. 1A, 1B, and 7, thebattery-powered motorized window treatment 200 shown in FIGS. 2A and 2B,the battery-powered motorized window treatment 300 shown in FIGS. 3A and3B, the battery-powered motorized window treatment 400 shown in FIGS. 6Aand 6B, the battery-powered motorized window treatment 500 shown in FIG.5A, the battery-powered motorized window treatment 5500 shown in FIG. 6,the battery-powered motorized window treatment 600 shown in FIGS. 8A-11,and/or the battery-powered motorized window treatment 1200 shown inFIGS. 17A and 17B). The motor drive unit 1500 may comprise a motor 1510(e.g., a direct-current (DC) motor) that may be coupled for raising andlowering a covering material. For example, the motor 1510 may be coupledto a roller tube (e.g., roller tube 610 shown in FIGS. 8A and 9) of themotorized window treatment for rotating the roller tube for raising andlowering a flexible material (e.g., a shade fabric). The motor driveunit 1500 may comprise a load control circuit, such as a motor drivecircuit 1520 (e.g., an H-bridge drive circuit) that may generate apulse-width modulated (PWM) voltage V_(PWM) for driving the motor 1510(e.g., to move the covering material between a fully-open andfully-closed position). In addition, the control circuit 1530 may beconfigured to generate a direction signal for controlling the directionof rotation of the motor 1510.

The motor drive unit 1500 may comprise a control circuit 1530 forcontrolling the operation of the motor 1510. The control circuit 1530may comprise, for example, a microprocessor, a programmable logic device(PLD), a microcontroller, an application specific integrated circuit(ASIC), a field-programmable gate array (FPGA), or any suitableprocessing device or control circuit. The control circuit 1530 may beconfigured to generate a drive signal V_(DRV) for controlling the motordrive circuit 1520 to control the rotational speed of the motor 1510(e.g. the motor drive circuit 1520 receives the drive signal V_(DRV) andcontrols, for example, an H-bridge circuit with appropriate PWM signalsin response to the drive signal). In examples, the drive signal V_(DRV)may comprise a pulse-width modulated signal, and the rotational speed ofthe motor 1510 may be dependent upon a duty cycle of the pulse-widthmodulated signal. In examples, the control circuit 1530 may directlycontrol the motor 1510 (e.g. in a configuration with no separate motordrive circuit 1520). For example, the control circuit may generate twoPWM signals for controlling the duty cycle and the polarity (e.g.controlling the speed and direction) of the motor 1510. In addition, thecontrol circuit 1530 may be configured to generate a direction signalV_(DIR) for controlling the motor drive circuit 1520 to control thedirection of rotation of the motor 1510. The control circuit 1530 may beconfigured to control the motor 1510 to adjust a present positionP_(PRES) of the covering material of the motorized window treatmentbetween a fully-open position P_(OPEN) and a fully-closed positionP_(CLOSED).

The motor drive unit 1500 may include a rotational sensing circuit 1540,e.g., a magnetic sensing circuit, such as a Hall effect sensor (HES)circuit, which may be configured to generate two signals V_(S1), V_(S2)(e.g., Hall effect sensor signals) that may indicate the rotationalposition and direction of rotation of the motor 1510. The rotationalsensing circuit 1540 (e.g., HES circuit) may comprise two internalsensing circuits for generating the respective signals V_(S1), V_(S2)(e.g., HES signals) in response to a magnet that may be attached to adrive shaft of the motor 1510. The magnet may be a circular magnethaving alternating north and south pole regions, for example. Forexample, the magnet may have two opposing north poles and two opposingsouth poles, such that each sensing circuit of the rotational sensingcircuit 1540 is passed by two north poles and two south poles during afull rotation of the drive shaft of the motor 1510. Each sensing circuitof the rotational sensing circuit 1540 may drive the respective signalV_(S1), V_(S2) to a high state when the sensing circuit is near a northpole of the magnet and to a low state when the sensing circuit is near asouth pole. The control circuit 1530 may be configured to determine thatthe motor 1510 is rotating in response to the signals V_(S1), V_(S2)generated by the rotational sensing circuit 1540. In addition, thecontrol circuit 1530 may be configured to determine the rotationalposition and direction of rotation of the motor 1510 in response to thesignals V_(S1), V_(S2).

The motor drive unit 1500 may include a communication circuit 1542(e.g., such as the control interface printed circuit board 654 shown inFIGS. 8A and 8B) that may allow the control circuit 1530 to transmit andreceive communication signals, e.g., wired communication signals and/orwireless communication signals, such as radio-frequency (RF) signals.For example, the motor drive unit 1500 may be configured to communicatemessages (e.g., digital messages) with external control devices (e.g.,other motor drive units) via the communication circuit 1542 and anantenna 1545 via wireless signals, such as RF signals. The communicationcircuit 1542 and/or the antenna 1545 may be communicatively coupled(e.g., electrically connected) to the control circuit 1530. Thecommunication circuit 1542 may be disposed within a cap (e.g., such asthe cap 150 shown in FIGS. 1B and 7, the cap 250 shown in FIGS. 2A and2B, the cap 350 shown in FIGS. 3A and 3B, the cap 450 shown in FIGS. 4Aand 4B, the cap 550 shown in FIG. 5A, and/or the cap 650 shown in FIGS.8A and 8B) of the motor drive unit 1500. Additionally or alternatively,the communication circuit 1542 may be internal to a housing of the motordrive unit 1500. The motor drive unit 1500 may also, or alternatively,be coupled to an external RF communication circuit (e.g., locatedoutside of the motor drive unit) for transmitting and/or receiving theRF signals.

The motor drive unit 1500 may communicate with one or more inputdevices, e.g., such as a remote control device, an occupancy sensor, adaylight sensor, and/or a shadow sensor. The remote control device, theoccupancy sensor, the daylight sensor, and/or the shadow sensor may bewireless control devices (e.g., RF transmitters) configured to transmitmessages to the motor drive unit 1500 via the RF signals. For example,the remote control device may be configured to transmit digital messagesvia the RF signals in response to an actuation of one or more buttons ofthe remote control device. The occupancy sensor may be configured totransmit messages via the RF signals in response to detection ofoccupancy and/or vacancy conditions in the space in which the motorizedwindow treatment is installed. The daylight sensor may be configured totransmit digital messages via RF signals in response to a measuredamount of light inside of the space in which the motorized windowtreatment is installed. The shadow sensor may be configured to transmitmessages via the RF signals in response to detection of a glarecondition outside the space in which the motorized window treatment isinstalled.

The motorized window treatment may be configured to control the coveringmaterial according to a timeclock schedule. The timeclock schedule maybe stored in the memory. The timeclock schedule may be defined by a user(e.g., a system administrated through a programming mode). The timeclockschedule may include a number of timeclock events. The timeclock eventsmay have an event time and a corresponding command or preset. Themotorized window treatment may be configured to keep track of thepresent time and/or day. The motorized window treatment may transmit theappropriate command or preset at the respective event time of eachtimeclock event.

The motor drive unit 1500 may further comprise a user interface 1544having one or more actuators (e.g., mechanical switches) that allow auser to provide inputs to the control circuit 1530 during setup andconfiguration of the motorized window treatment (e.g., in response toactuations of one or more buttons (e.g., the control button 152 shown inFIG. 1B). The control circuit 1530 may be configured to control themotor 1510 to control the movement of the covering material in responseto a shade movement command received from the communication signalsreceived via the communication circuit 1542 or the user inputs from thebuttons of the user interface 1544. The control circuit 1530 may beconfigured to enable (e.g., via the control button 152 and/or the userinterface 1544) a user to pair the motorized window treatment with aremote control device and/or other external devices to allow forwireless communication between the remote control device and/or otherexternal devices and the communication circuit 1542 (e.g., an RFtransceiver). The user interface 1544 (e.g., the control button 152) maybe configured to provide a status indication to a user. For example,user interface 1544 (e.g. the control button 152) may be configured toflash and/or change colors to provide the status indication to the user.The status indication may indicate when the motorized window treatmentis in a programming mode. The user interface 1544 may also comprise avisual display, e.g., one or more light-emitting diodes (LEDs), whichmay be illuminated by the control circuit 1530 to provide feedback tothe user of the motorized window treatment system.

The motor drive unit 1500 may also comprise a position detect circuit1546 for detecting when a roller tube of the motorized window treatmentis not in the operating position. The position detect circuit 1546 maybe located in a motor drive unit housing end (e.g., the first end 112and/or the cap 150 shown in FIG. 1B) which may be attached to a mountingbracket (e.g., mounting brackets 130A, 130B, 230A, 330A, 430A, 530A,5530A, 630, 700, 800, 900, 1000, 1100, 1200). For example, the positiondetect circuit 1546 may comprise a magnetic sensing circuit (e.g., aHall-effect sensor circuit) configured to detect when the mountingbracket is in an extended position and the position detect circuit 1546is not in close proximity to a magnet located inside of an arm (e.g.,arms 632, 714, 814, 914, 1014, 1114, and/or front portion 1214) of themounting bracket. The position detect circuit 1546 may be configured togenerate a position detect signal V_(POS), which may be received by thecontrol circuit 1530. The control circuit 1530 may be configured todisable (e.g., automatically disable) the operation of the motor 1510 ofthe motor drive unit 1500 in response to the position detect signalV_(POS), such that the covering material cannot be raised or loweredwhen the roller tube is not in an operating position (e.g., in theextended position). The control circuit 1530 may be configured to enablethe operation of the motor 1510 in response to the position detectsignal V_(POS) when the roller tube is in the operating position.

The motor drive unit 1500 may comprise a memory (not shown) configuredto store the present position P_(PRES) of the covering material and/orthe limits (e.g., the fully-open position P_(OPEN) and the fully-closedposition P_(CLOSED)), association information for associations withother devices and/or instructions for controlling the motorized windowtreatment. The memory may be implemented as an external integratedcircuit (IC) or as an internal circuit of the control circuit 1530.

The motor drive unit 1500 may comprise a compartment 1564 (e.g., whichmay be an example of the battery compartment 211 of the window treatment200 shown in FIGS. 2A and 2B) that is configured to receive a DC powersource. In some examples, the compartment 1564 may be internal to themotor drive unit 1500. In other examples, the compartment 1564 may beexternal to the motor drive unit 1500. In the example shown in FIGS. 2Aand 2B, the DC power source is one or more batteries 1560. In addition,alternate DC power sources, such as a solar cell (e.g., a photovoltaiccell), an ultrasonic energy source, and/or a radio-frequency (RF) energysource, may be coupled in parallel with the one or more batteries 1560,or in some examples be used as an alternative to the batteries 1560. Thealternate DC power source may be used to perform the same and/or similarfunctions as the one or more batteries 1560. In this example, thecompartment 1564 may be configured to receive one or more batteries 1560(e.g. four “D” batteries), such as the batteries 260, 360, 460, 560,5560 of FIGS. 2A, 2B, 3A, 3B, 4A, 4B, 5A, 6. The batteries 1560 mayprovide a battery voltage V_(BATT) to the motor drive unit 1500.

The control circuit 1530 may be configured to determine when one or moreof the batteries 1560 are not installed in the compartment 1564 when inthe operating position. For example, the control circuit 1530 may beconfigured to determine that one or more of the batteries 1560 aremissing when the magnitude of the battery voltage V_(BATT) drops toapproximately zero volts (e.g., there is an open circuit between thebattery contacts). The control circuit 1530 may be configured todetermine the magnitude of the battery voltage V_(BATT) in response to ascaled battery voltage V_(BATT-S) received via a scaling circuit 1566(e.g., a resistive divider circuit). The scaling circuit 1566 mayreceive the battery voltage V_(BATT) and may generate the scaled batteryvoltage V_(BATT-S). The control circuit 1530 may be configured todisable (e.g., automatically disable) the operation of the motor 1510 ofthe motor drive unit 1500 in response to the scaled battery voltageV_(BATT-S), such that the covering material cannot be raised or loweredwhen one or more of the batteries 1560 are not installed in the batterycompartment 1564, which may prevent depletion of the intermediatestorage element 1554. The control circuit 1530 may be configured toenable the operation of the motor 1510 in response to the scaled batteryvoltage V_(BATT-S) when all of the batteries 1560 are installed.

The motor drive unit 1500 may comprise a filter circuit 1570, a currentlimiting circuit, such as a power converter circuit 1552, and an energystorage element 1554 (e.g., an intermediate energy storage element suchas the intermediate storage device 694 shown in FIG. 8A). In someexamples, the motor drive unit 1500 may include a second powerconverter, such as a boost converter circuit 1558. Also, in someexamples, the second power converter may be omitted from the motor drivecircuit 1500. The energy storage element 1554 may comprise anycombination of one or more super capacitors, one or more rechargeablebatteries, and/or other suitable energy storage devices.

The filter circuit 1570 may receive the battery voltage V_(BATT). Thepower converter circuit 1552 may draw a battery current I_(BATT) fromthe batteries 1560 through the filter circuit 1570. The filter circuit1570 may filter high and/or low frequency components of the batterycurrent I_(BATT). In some examples, the filter circuit 1570 may be alow-pass filter. Also, in some examples, the filter circuit 1570 may beomitted from the motor drive circuit 1500.

The power converter circuit 1552 may be configured to limit the currentdrawn from the batteries 1560 (e.g. allowing a small constant current toflow from the batteries 1560). The power converter circuit 1552 mayreceive the battery voltage V_(BATT) (e.g. V_(IN)) via the filtercircuit 1570. In some examples, the power converter circuit 1552 maycomprise a step-down power converter, such as a buck converter. Thepower converter circuit 1552 may be configured to charge the energystorage element 1554 from the battery voltage V_(BATT) to produce astorage voltage V_(S) across the energy storage element 1554 (e.g.,approximately 3.5 volts). The motor drive circuit 1520 may draw energyfrom the energy storage element 1554 (e.g., via the boost convertercircuit 1558) to drive the motor 1510. As such, the power convertercircuit 1552 may be configured to limit the current drawn from thebatteries 1560, for example, by producing a storage voltage V_(S) anddriving the motor 1510 using the storage voltage V_(S) stored across theenergy storage element 1554. In most cases, for instance, the motordrive circuit 1520 may drive the motor 1510 by drawing current from theenergy storage element 1554 and not drawing any current directly fromthe batteries 1560. Further, it should be appreciated that, in someexamples, the power converter circuit 1552 may be omitted for anothercurrent limiting circuit, such as in instances where the battery voltageV_(BATT) is the same as the storage voltage V_(S) and power conversion(e.g., a step-up or step-down) is not needed to drive the motor 1510.

The motor drive unit 1500 may be configured to control when and how theenergy storage element 1554 charges from the batteries 1560. The controlcircuit 1530 may control when and how the energy storage element 1554charges from the batteries 1560 based on the storage voltage V_(S) ofthe energy storage element 1554, such as when the storage voltage V_(S)of the energy storage element 1554 falls below a low-side thresholdvalue (e.g., approximately 2.8 volts). For example, the control circuit1530 may be configured to receive a scaled storage voltage V_(SS) via ascaling circuit 1556 (e.g., a resistive divider circuit). The scalingcircuit 1556 may receive the storage voltage V_(S) and may generate thescaled storage voltage V_(SS). The control circuit 1530 may determinethe magnitude of the storage voltage V_(S) of the energy storage element1554 based on the magnitude of the scaled storage voltage V_(SS). Whenthe control circuit 1530 determines that the magnitude of the storagevoltage V_(S) of the energy storage element 1554 falls below thelow-side threshold value, the control circuit 1530 may control acharging enable signal V_(EN) (e.g., drive the charging enable controlsignal V_(EN) high) to enable the power converter circuit 1552. When thepower converter circuit 1552 is enabled, the power converter circuit1552 may be configured to charge the energy storage element 1554 (e.g.from the batteries 1560). When the power converter circuit 1552 isdisabled, the power converter circuit 1552 may be configured to ceasecharging the energy storage element 1554 (e.g. from the batteries 1560).

The motor drive unit 1500 may utilize the energy storage element 1554 todraw a small constant current from the batteries 1560 over a long periodof time to extend the lifetime (e.g., and increase the total energyoutput) of the batteries 1560. For example, the motor drive unit 1500(e.g., the power converter circuit 1552 and/or the motor drive circuit1520) may limit the current drawn by the power converter circuit 1552.The motor drive unit 1500 may draw current from the batteries 1560 thatis less than the limit, but not more.

When enabled, the power converter circuit 1552 may be configured toconduct an average current I_(AVE) (e.g., having a magnitude ofapproximately 15 milliamps) from the batteries 1560. The magnitude ofthe average current I_(AVE) may be much smaller than a magnitude of adrive current required by the motor drive circuit 1520 to rotate themotor 1510. When the motor drive circuit 1520 is driving the motor 1510,the magnitude of the storage voltage V_(S) of the energy storage element1554 may decrease with respect to time. When the motor drive circuit1520 is not driving the motor 1510 and the power converter circuit 1552is charging the energy storage element 1554, the magnitude of thestorage voltage V_(S) may increase (e.g., slowly increase). When thestorage voltage V_(S) of the energy storage element 1554 falls below alow-side threshold value (e.g. approximately 2.8V), the control circuit1530 may enable the power converter circuit 1552 to begin charging theenergy storage element 1554. The storage voltage V_(S) may fall belowthe low-side threshold value after powering movements of the coveringmaterial, powering low-voltage components, and/or due to leakagecurrents over time. When the storage voltage V_(S) of the energy storageelement 1554 rises above a high-side threshold value (e.g.,approximately 3.5 volts), the control circuit 1530 may cease driving thecharging enable signal V_(EN) high to disable the power convertercircuit 1552 and stop the charging of the energy storage element 1554from the batteries 1560.

The motor drive unit 1500 may further comprise the boost convertercircuit 1558 that receives the storage voltage V_(S) and generates amotor voltage V_(MOTOR) (e.g., approximately 5 volts) for powering themotor 1510. The motor voltage V_(MOTOR) may be larger than the storagevoltage V_(S). In some examples, a switch (e.g., a single pole doublethrow switch) may connect the batteries 1560 and the energy storageelement 1554 to the boost converter 1558 (e.g., if the required motorvoltage level exceeds the present battery voltage V_(BAT)). When thecontrol circuit 1530 controls the motor drive circuit 1520 to rotate themotor 1510, the boost converter circuit 1558 may conduct current fromthe energy storage element 1554 to generate the motor voltage V_(MOTOR).As noted above, in some examples, the motor drive unit 1500 may notinclude the boost converter circuit 1558, for example, based on thevoltage requirements of the motor 1510.

The motor drive unit 1500 may also comprise a controllable switchingcircuit 1562 coupled between the batteries 1560 and the motor drivecircuit 1520. The control circuit 1530 may generate a switch controlsignal V_(SW) for rendering the controllable switching circuit 1562conductive and non-conductive. The control circuit 1530 may beconfigured to render the controllable switching circuit 1562 conductiveto bypass the filter circuit 1570, the power converter circuit 1552, theenergy storage element 1554, and/or the boost converter circuit 1558 toallow the motor drive circuit 1520 to draw current directly from thebatteries (e.g., when the energy storage element 1554 is depleted). Forexample, the control circuit 1530 may render the controllable switchingcircuit 1562 conductive when the control circuit 1530 determines thatthe magnitude of the storage voltage V_(S) of the energy storage element1554 (e.g., based on the magnitude of the scaled storage voltage V_(SS))is depleted below a threshold and the control circuit 1530 has receivedan input or command to operate the motor 1510 and, for example, does nothave enough energy to complete a movement or an amount of movement ofthe covering material). For example, the control circuit may determineif the energy storage element 1554 has enough energy to complete amovement or an amount of movement of the covering material by comparinga present storage level of the energy storage element 1554 (e.g., thestorage voltage V_(S)) to a threshold. The threshold may indicate astorage level sufficient to complete a full movement of the coveringmaterial from the fully-closed position to the fully-open position(e.g., a fixed threshold). The threshold may be constant or may vary,for example, depending on the amount of movement of the coveringmaterial required by the received command, such that the threshold(e.g., a variable threshold) may indicate a storage level sufficient tocomplete the movement required by the received command.

If the energy storage element 1554 is not sufficiently charged (e.g.,does not have enough energy to move the covering material), the controlcircuit 1530 may close the controllable switching circuit 1562 at toallow the electrical load (e.g., the motor) to draw current directlyfrom the batteries 1560. Closing the controllable switching circuit 1562may bypass the energy storage element 1554, such that the stored energyof the energy storage element 1554 is not used for driving the motor1510 to move the covering material.

The control circuit 1530 may be configured to determine when one or moreof the batteries 1560 are not installed in the compartment 1564 when inthe operating position. For example, the control circuit 1530 may beconfigured to determine that one or more of the batteries 1560 aremissing when the magnitude of the battery voltage V_(BATT) drops toapproximately zero volts (e.g., there is an open circuit between thebattery contacts). The control circuit 1530 may be configured todetermine the magnitude of the battery voltage V_(BATT) in response to ascaled battery voltage V_(BATT-S) received via a scaling circuit 1566(e.g., a resistive divider circuit). The scaling circuit 1566 mayreceive the battery voltage V_(BATT) and may generate the scaled batteryvoltage V_(BATT-S). The control circuit 1530 may be configured todisable (e.g., automatically disable) the operation of the motor 1510 ofthe motor drive unit 1500 in response to the scaled battery voltageV_(BATT-S), such that the covering material cannot be raised or loweredwhen one or more of the batteries 1560 are not installed in the batterycompartment 1564, which may prevent depletion of the intermediatestorage element 1554. The control circuit 1530 may be configured toenable the operation of the motor 1510 in response to the scaled batteryvoltage V_(BATT-S) when all of the batteries 1560 are installed.

The motor drive unit 1500 may comprise a power supply 1580 (e.g., alow-voltage power supply). The power supply 1580 may receive the batteryvoltage V_(BATT). The power supply 1580 may be configured to produce alow-voltage supply voltage V_(CC) (e.g., approximately 3.3 volts) forpowering low-voltage circuitry of the motor drive unit 1500, such as theuser interface 1544, the communication circuit 1542, and the controlcircuit 1530. Further, in some examples, the power supply 1580 may beomitted from the motor drive unit 1500 (e.g. if the low-voltagecircuitry of the motor drive unit 1500 is able to be powered directlyfrom the storage voltage V_(S)). Additionally or alternatively, themotor drive unit 1500 may comprise a power supply (not shown) that mayreceive the storage voltage V_(S) and generate the low voltage V_(CC)(e.g., approximately 3.3 V) for powering the control circuit 1530 andother low-voltage circuitry of the motor drive unit 1500, e.g., the userinterface 1544, the communication circuit 1542, and the control circuit1530.

The user interface 1544, the communication circuit 1542, the antenna1545, and the position detect circuit 1546 may be part of a cap circuit1590, which may be mounted to a first printed circuit board (e.g., thecontrol interface printed circuit board 654 shown in FIG. 8B) located inan end portion of the motor drive unit 1500 (e.g., such as the motordrive unit end portion 150 shown in FIGS. 1B and 7 and/or the cap 250shown in FIGS. 2A and 2B). The other circuitry of the motor drive unit1500 may be mounted to a second printed circuit board (e.g., the motordrive printed circuit board 692). Although the communication circuit1542 is shown in FIG. 29 as part of the cap circuit 1590, it should beappreciated that the communication circuit 1542 may not be part of thecap circuit 1590 and may be mounted to the second printed circuit board,while the antenna 1545 may be part of the cap circuit 1590 and locatedon the first printed circuit board.

FIG. 30 is a flowchart depicting an example method 1600 for controllinga motor drive unit of a motorized window treatment (e.g., the motordrive unit 151 of the motorized window treatment 100 shown in FIG. 1B,the motor drive unit 5590 of the motorized window treatment 5500 shownin FIG. 6, the motor drive unit 690 of the motorized window treatment600 shown in FIGS. 8A and 8B, and/or the motor drive unit 1500 shown inFIG. 29). The motorized window treatment may have a window treatmentassembly (e.g., the roller tube assembly 111 that may be changed from anoperating position (e.g., in which a covering material of the motorizedwindow treatment may be moved) to an extended position (e.g., in whichone or more batteries of the motor drive unit may be accessed). Themethod 1600 may be implemented by one or more devices. The method 1600may be executed by a control circuit of the motor drive unit (e.g., thecontrol circuit 1530 shown in FIG. 29). For example, the method 1600 maybe executed by the control circuit of the motor drive unit to enableand/or disable operation of a motor of the motor drive unit. The method1600 may be executed at 1602, for example, periodically (e.g., every onesecond).

At 1604, the control circuit may determine if the window treatmentassembly is in the extended position (e.g., and not in the operatingposition). For example, the motor drive unit may comprise a positiondetect circuit (e.g., the position detect circuit 1546 shown in FIG. 29)for detecting when the window treatment assembly is not in the operatingposition. The position detect circuit may be located in a motor driveunit housing end (e.g., the first end 112 and/or the cap 150 shown inFIG. 1B) which may be attached to a mounting bracket (e.g., mountingbrackets 130A, 130B, 230A, 330A, 430A, 530A, 5530A, 630, 700, 800, 900,1000, 1100, 1200). For example, the position detect circuit may comprisea magnetic sensing circuit (e.g., a Hall-effect sensor circuit)configured to detect when the mounting bracket is in an extendedposition. The position detect circuit may determine when it is not inclose proximity to a magnet located inside of an arm (e.g., arms 632,714, 814, 914, 1014, 1114, and/or front portion 1214) of the mountingbracket. The position detect circuit may be configured to generate aposition detect signal (e.g., the position detect signal V_(POS)), whichmay be received by the control circuit. The control circuit maydetermine if the window treatment assembly is in the extended position(e.g., not in the operating position) in response to the position detectsignal at 1604. If the window treatment assembly is in the extendedposition at 1604, the control circuit may disable the operation of themotor of the motor drive unit at 1610, such that the covering materialcannot be raised or lowered when the window treatment assembly is not inthe operating position (e.g., in the extended position). The method 1600may end at 1612.

If the window treatment assembly is in the operating position at 1604,the control circuit may determine if one or more of the batteries arenot installed in a battery compartment of the motor drive unit at 1606.For example, the control circuit may be configured to determine that oneor more of the batteries are not installed when the magnitude of abattery voltage received from the batteries (e.g., the battery voltageV_(BATT)) is approximately zero volts. The control circuit may beconfigured to determine the magnitude of the battery voltage in responseto a scaled battery voltage (e.g., the scaled battery voltage V_(BATT-S)that may be received via the scaling circuit 1566). The control circuitmay determine that one or more of the batteries are not installed inresponse to a scaled battery voltage at 1606. If the control circuitdetermines that one or more of the batteries are not installed at 1606,the control circuit may disable the operation of the motor of the motordrive unit at 1610, such that the covering material cannot be raised orlowered when one or more of the batteries are not installed in thebattery compartment, for example, to prevent depletion of anintermediate storage element of the motor drive unit (e.g., theintermediate storage element 1554). The method 1600 may end at 1612.

If the roller tube assembly is determined at 1604 to be in the operatingposition and all of the batteries are determined at 1606 to beinstalled, the control circuit may enable the operation of the motor at160, such that the covering material may be raised and lowered. Themethod 1600 may end at 1612. Alternatively, block 1606 may be omittedfrom the method 1600, such that the control circuit may enable theoperation of the motor at 1608 when the roller tube assembly is in theoperation position at 1604.
